Question 30
Easy

Figure 3 shows a heating element connected to a d.c. power supply.

The power supply provides a potential difference of 9.0 V.

The current in the heating element is 0.60 A.

Calculate the resistance of the heating element. Use the equation:

R=VI R = \frac{V}{I} R=IV​

Figure 3: A simple circuit diagram consisting of a single closed loop. At the top is a d.c. power supply, and at the bottom is a rectangular box representing a heating element.
