Why is the voltage output from an arduino positive? [closed]
It is common in analog circuits to call the midpoint of the power supply "Ground", then we will have both positive and negative voltages. When you put the common lead of your meter on the positive terminal of the 9 volt battery, you effectively declared the positive terminal as "Ground", so the meter says the negative terminal is -9 volts.

This is the point where you should get out a multimeter, some resistors, and a battery (or power supply.) 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.
How to Tell Positive and Negative Terminals on a Car Battery
Park another vehicle by your car and turn everything off. Park the other car close enough that a set of jumper cables can reach both batteries. Cut the engine on the booster car and turn off all the accessories in both cars, like the interior lights, radio, and AC. Most cars have their batteries under the hood, but some may have the battery in the trunk.

Some controllers are negative ground, some are positive ground. That means they go strait thru that side and switch/regulate on the other side. Positive ground will have battery voltage on solar +, Solar - could be -98v. Use a dual breaker. Negative ground is safer and maybe it needs only 1 breaker on solar +.
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

Battery terminals on the wrong side?? Every website that sells
its not about normal or abnormal. batteries come with two types of configurations. one is generally not labeled while the other is a ''R'' or reversed. batteries from pretty much all companies sell as the same but are either one model number up or down such as a group 35 and a 36r are the same exact battery form factor but have reversed terminals.
why would you ever put the resistor on the positive side
There are various equations relating voltage current, resistance and power, but the most useful one here is P = I²R, where I is the current, R is the resistance of a given component, and P is the power delivered. For any given resistance, the power depends on the current (squared), and not where it is in the circuit.

A User''s Guide to Compensating Low-Dropout Regulators
pole is frequency dependent, varying from 0 to -90° (with a phase shift of -45° at the pole frequency). The most important point is that nearly all of the phase shift added by a pole (or zero) occurs within the frequency range one decade above and one decade below the pole (or zero) frequency. NOTE: a single pole can add only -90°

Anatomy of a Battery
On a 9-volt or car battery, however, the terminals are situated next to each other on the top of the unit. If you connect a wire between the two terminals, the electrons will flow from the negative end to the positive end as fast as they can. This will quickly wear out the battery and can also be dangerous, particularly on larger batteries.
Why to disconnect the negative/ground terminal, not positive?
In many cases, it doesn''t matter whether the positive or negative power connection is broken. Good examples are driving a solenoid, relay, or LED. When a circuit is more complex and has connections back to the driving circuit, then it''s often worth the extra complexity of switching the power and keeping the ground always connected.
Working With a Positive Ground
For instance, while a 1950 Chevrolet truck may have a six-volt system with a negative ground, a similar GMC truck could have a positive ground system.The British continued to "earth" their systems to the positive pole until they switched their charging systems to alternators in the later ''60s.
