Question

The potential difference between the terminals of an electric heater is 120 V when it draws a current of 8 A from the source. What current will the heater draw if the potential difference is increased to 240 V?
​

Answer 1

Answer:

= 120/15 = 8A. Potential difference is increased to 120V then the current drawn is 8A

Answer 2

Answer:

16A

Explanation:

I guess , Current will be 16 A ... as current was 8A when potential difference is 120V.

Thus, the current drawn by the heater is doubled when the potential difference across the terminals is doubled.
