Chapter 22, Problem 64A

To determine

Current through the resistor.

Answer to Problem 64A

  $I=0.5\text{A}$

Explanation of Solution

Given:

Resistance of resistor, $R=150\Omega$

Source voltage, $V=75\text{V}$

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,

  $\begin{array}{l}75=I\times 150\\ \Rightarrow I=\frac{75}{150}\text{V}\\ =0.5\text{A}\end{array}$

Conclusion:

Therefore, the current through the resistor is $I=0.5\text{A}$
