Chapter 21.2, Problem 26PP

To determine

Work done by battery.

Answer to Problem 26PP

  $W=4.5\text{J}$

Explanation of Solution

Given:

Charge, $q=3\text{C}$

Potential difference, $\Delta V=1.5\text{V}$

Formula Used:

The work done by battery is given as,

  $W=q\Delta V$

Where, $W$ is work done by battery, $q$ is charge and $\Delta V$ is potential difference.

Calculation:

On substituting the given values in above relation,

  $\begin{array}{c}W=3\times 1.5\\ =4.5\text{J}\end{array}$

Conclusion:

Therefore, the work done by battery in moving the given charge is $W=4.5\text{J}$ .
