Earthing negative pole of battery
Telco 48 VDC systems are generally positive ground. I''ve been told it had something to do with minimizing battery terminal corrosion, but I doubt it matters much with modern batteries that are sealed much better than the old fashioned glass jar flooded lead acid ones. The positive ground system did mess with the heads of a number of telco techs.
electrostatics
this potential will not go away simply because you "grounded" the negative terminal because there''s no electrons flowing in a loop from negative to positive outside of the battery, and positive to negative within the battery. There are some corner cases where a reasonably large number of electrons might flow out of the battery into the ground.
Earthing & Grounding Basics
They simply pick up the Earth''s energy through the ground port of a properly grounded outlet or from a ground rod placed directly in the Earth and deliver it via a cord to the conductive Earthing® pad, mat, sheet, or band specially designed for human grounding.
ground
Assemble a few examples like the circuit you were given, and measure the voltages using different "ground points." Use the minus pole of the battery, then the plus pole of the battery, then some point in between. The sum will always be your battery voltage, though the measured voltages will depend on the resistor values.

"Ground" vs. "Earth" vs. common vs. negative terminal
A. The positive terminal in a circuit is what creates voltage. Voltage is a potential, so given that it is the positive ions in, say, a battery, which are generally fixed in place, it makes sense that the + terminal in a circuit would create voltage.. B. The negative terminal in a circuit is what provides current. Current is the flow of electrons, and that flow is towards the terminal …
Why is it not possible to measure voltage between one battery pole …
If a DC multimeter is attached to the plus pole of a battery and the other pin to ground, then in my understanding there is a positive potential on the positive battery pole and a zero potential at .

So, if there''s a transient flow of electrons from the negative terminal to ground that raises the voltage of that terminal with respect to ground by some amount,* then I would expect an equivalent amount of positive charge (i.e., half as many "+2" ions) to flow across the salt bridge, and raise the voltage of the positive terminal by the same ...
eli5: ground vs negative terminal. are they the same thing?
Not necessarily but, by convention, generally yes. Ground is nothing more than a baseline reference for all the voltages on a circuit. You start with whatever voltage your power source provides and call negative to the 0V pole and positive to +24V (or whatever) pole. Ground is always 0V so ground, negative and 0V all mean the same.

Every piece of electronics whether it be a microprocessor or LCD screen always has a positive power supply and a ground pin. The positive power supply or VDD is clearly where you supply something like 5 volts. It would be like taking a 5 volt battery and connecting the positive end with a wire to the VDD pin.
Negative/Positive Ground
By Norman NockOriginally published in the Austin-Healey MagazineAn electrical circuit needs a feed wire and a return. The return can be a wire itself, creating an insulted return system, or it can be a common grounding element—in this case the chassis of the car. Cars built after the late ''60s used the negative pole of the battery as ground to the chassis. Negative …
Ignition Coil Basics
This is the terminal that receives voltage from the battery. The primary wire is then coiled around the iron core and its other end is attached to the terminal marked "-" or "Dis." The voltage flows from this terminal to the breaker points inside the distributor. (Positive ground is the reverse.) Failures and Fixes
Should negative trickle charger clips be attached to the battery ...
A car I had in the 60''s - I think it was an original mini or Beetle actually had positive battery terminal to chassis. Blindly connecting charger negative to chassis and positive to either pole of the battery would have caused problems (read fire, smoke, brokenness) in the charger, battery or car - especially in the old equipment we used back then.

What is the positive pole in a battery called? – Wise-Answer
The pole with more electrons is said to have negative polarity. The pole with fewer electrons then has a positive polarity. When the two poles are connected by a wire, electrons flow from the negative pole toward the positive pole. Which line is positive on a battery? One is marked positive (+), the other negative (-).
What is a charge controller with a "positive ground"?
To expand on @fat_old_sun''s comment: a "positive grounded" aka "common positive" controller simply means that the solar panel positive and the battery positive and the controller''s load terminal positive are all connected in common; i.e. the controller is using low-side switching using cheaper/more powerful N-channel FETs. Note the controller grounding does …
ELI5: Where does ground go in a car battery? : r/explainlikeimfive
Electrons move from negative battery pole to the positive pole in a circuit. The "ground" has a different meaning compared to normal household electricity (alternating current). Nearly all cars/vehicles since the second world war are "negative ground", meaning all the chassis is "grounded" - connected to the negative battery pole.
Accidentally touched positive battery terminal with...
Hey everyone. Just had a quick question. I don''t know what i was thinking. I wanted to make sure the connections were tight on my battery and I started to tighten the positive terminal with the little wrench included in the toolkit and as I was making sure the little bolt was tight, LOTS of sparks flew (and crackling) and it scared the hell out of me.
Why do we place a negative cable to the ground instead of the negative …
Avoiding sparks near the battery is the main reason for the common advice to make the last connection to ground away from the battery on the vehicle with the dead battery. It is best to make this connection directly to the engine or to some sturdy metal part bolted to the engine.
Earth battery
An earth battery is a pair of electrodes made of two dissimilar metals, such as iron and copper, which are buried in the soil or immersed in the sea.Earth batteries act as water-activated batteries.If the plates are sufficiently far apart, they can tap telluric currents. [citation needed] Earth batteries are sometimes referred to as telluric power sources and telluric generators.

For example, positive- or negative-grounded PV modules will cause current leakage to the inverter. Grounding of the PV module frame is permitted and frequently required by local law.The battery is galvanically isolated from the inverter and PV input, therefore the battery positive or negative terminal may be grounded if required.
Where To Ground Your Car Battery?
The most common way to ground the battery is by using your chassis'' bolt holes as grounding points. You will need to find out which ones these are and then use them accordingly. Once in place, apply a cable clamp on each one of those bolts (on each end of the cable) and then attach them to the battery''s ground terminal.
Will a battery discharge if one pole is connected to the ground?
With static electricity it''s clear that free electrons would go to the ground. But I have significant doubts that an accumulator battery will discharge if one of it''s electrodes is …
Car battery
As long as you don''t touch the battery positive terminal at the same time you will be OK and since the battery positive terminal usually has a red cover on it there is little risk. Once the battery negative is disconnected, accidentally touching the battery positive to the cars bodywork using a tool is no longer dangerous.
Why do we connect a battery to ground when jumping a car?
The circuitry in the car is also grounded to the chassis, albeit with some other protection in between, but this has nothing to do with the current flowing from one car to another during a "jump." ... During jump-starting, we connect the boosting battery to ground rather than to the dead battery''s - terminal for the simple reason that this ...
