Chapter 22.1, Problem 13PP

To determine

Current through the circuit.

Answer to Problem 13PP

  $I=0.3636\text{A}$

Explanation of Solution

Given:

Battery voltage, $V=12\text{V}$

Lamp resistance, $R=33\Omega$

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,

  $\begin{array}{c}12=I\times 33\\ I=\frac{12}{33}\text{A}\\ =0.3636\text{A}\end{array}$

Conclusion:

Therefore, the current through the circuit is $I=0.3636\text{A}$ .
