Neutral Vs Ground Wire: What That White Wire Is Actually For
This is why the US National Electric Code Article 250 requires the ground wire to also be tied to the neutral wire at the service panel . To follow the current path—the current flows through the appliance ground wire to the breaker box where it joins the neutral path. The current becomes too high at this point and the breaker trips.
How Much Current Is available in Series-Connected Batteries?
$begingroup$ So in other words, as the cell in the parallel bank approaches total charge depletion, it would not affect the bank V when it is 100% depleted,but it would eventually cause that bank to be depleted sooner than the other banks in the battery. When the charge of that bank is depleted, it will output less V & cause the battery to have a lower V …

Why is there a neutral and live wire in Alternating Current?
The reason that the line wire is dangerous is that when you hold it you become the neutral and the voltage on the line pushes current through you to earth (or pulls current through you from earth depending on the side of the AC cycle you are on). When you hold the neutral, the voltage is 0V and no current flows.
