Chapter 34, Problem 33A

Calculate the current in a toaster that has a heating element of 14 ohms when connected to a 120-V outlet.

To determine

To Calculate: The current in a toaster.

Answer to Problem 33A

  $8.6\text{A}$

Explanation of Solution

Given:

Resistance of the heating element, $R=14\Omega$

Voltage, $V=120\text{V}$

Formula Used:

Current can be calculated using Ohm’s law:

  $I=\frac{V}{R}$

Here, V is the voltage and R is the resistance.

Calculations:

Substitute the values and solve:

  $\begin{array}{l}I=\frac{V}{R}\\ I=\frac{\text{120}\text{V}}{\text{14}\Omega }=8.6\text{A}\end{array}$

Conclusion:

Thus, the current in a toaster is $8.6\text{A}$ .
