Question

A charge travels from the positive terminal of a 6�-V battery, through a light bulb, and through the battery back to the positive terminal. The total change in voltage experienced by the charge during this journey is

A) -1V
B)1V
C)-6V
D)6V
E)0V

Answer 1

0 V

Step-by-step explanation:

- The potential for the charge to flow through the circuit and back to the same terminal means that work-done per unit length i.e Potential difference is zero because the total work-done for the charge to complete the loop and back at the same point " Terminal "

Potential difference = 6 - 6 = 0 V
