Question

Calculate the work done to move a charge $5$ C between two points A and B, if both the points are maintained at same potential of $6$ V

• A. Zero
• B. $6$J
• C. $3$J
• D. $12$ J

Answer 1

Answer: (A)

Zero

Given two points $A$ and $B$ maintained at same potential i.e, $6V$. We have to calculate the work done to move a charge between $A$ and $B$.

Since work done to move $5C$ between two points $A$ and $B=$ change in potential at two points $\times$ charge

Since change in potential between points $A$ and $B$ is zero, since both the points are maintained at constant potential.

So, the work done is zero.
