Question 59
Easy

Figure 1 shows an industrial heating element connected to a steady d.c. voltage source.

Figure 1: An industrial heating element connected in series to a d.c. power supply

The power supply maintains a constant potential difference of 18.0 V across the element.

The current flowing through the element is measured to be 0.12 A.

Calculate the resistance of the heating element.

Use the equation:

R=VI R = \frac{V}{I} R=IV​
