Chapter 22, Problem 61A

To determine

Voltage of the battery.

Answer to Problem 61A

  $V=24\text{V}$

Explanation of Solution

Given:

Resistance of resistor, $R=60\Omega$

Circuit current, $I=0.4\text{A}$

Formula Used:

Ohm’s law is given as,

  $V=IR$

Where, $V$ is applied voltage, $I$ is current and $R$ is resistance.

Calculation:

On substituting the values in above relation,

  $\begin{array}{l}V=0.4\times 60\\ =24\text{V}\end{array}$

Conclusion:

Therefore, the voltage of the battery is $V=24\text{V}$
