Chapter 34, Problem 34A

Calculate the current in the coiled heating element of a 240-V stove. The resistance of the element is 60 ohms at its operating temperature.

To determine

To Calculate: The current in the coiled heating element of a stove.

Answer to Problem 34A

  $4\text{A}$

Explanation of Solution

Given:

Resistance of the heating element, $R=60\Omega$

Voltage, $V=240\text{V}$

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:

  $\begin{array}{l}I=\frac{V}{R}\\ I=\frac{\text{240}\text{V}}{60\Omega }=4\text{A}\end{array}$

Conclusion:

Thus, the current in the heating element of stove is $4\text{A}$ .
