Question

the potential difference the terminal of an electric heater is 75v when it draw a current of 5A from the source. what current will the heater draw ,of the potential difference is increased to 150v?​

Answer 1

Answer:

Explanation:

V =60 v

I=4 A

R = V/I 60/4 = 15Ω

When potential difference is increased to 120V

I = V / R

= 120 / 15

= 8A

The current through the heater becomes 8A
