Chapter 35, Problem 48A

A $30\text{-}\Omega$ resistor is connected to a 240-V source. How much current flows in the resistor?

To determine

The current flow in the resistor.

Answer to Problem 48A

The current flow in the resistor is $8\text{A}$ .

Explanation of Solution

Given info:

Voltage of the source, $V=240\text{V}$

Resistance of the resistor, $R=30\Omega$

Formula used:

The expression to calculate the current flow in the resistor is,

  $I=\frac{V}{R}$

Calculation:

Substitute given values in the above expression.

  $\begin{array}{c}I=\frac{240\text{V}}{30\Omega }\\ =8\text{A}\end{array}$

Conclusion:

The current flow in the resistor is $8\text{A}$ .
