Voltage and Charge Indicator Lamp Explanation

Is it true that when the voltage on each side of the charge indicator lamp is equal, the lamp is turned off?

A. True

B. False

Answer:

The correct answer is A. True.

When the voltage on each side of the charge indicator lamp is equal, the lamp is indeed turned off. This occurs because when the voltage across the lamp is the same on both sides, there is no potential difference present to drive current through the lamp.

According to Ohm's Law (V = IR), if the voltage across the lamp is zero, the current flowing through the lamp will also be zero. As a result, the lamp remains inactive and does not light up.

The equal voltage on both sides of the lamp ensures that there is no potential gradient to push any current through it, which keeps the lamp turned off.
