Question

the potential difference between the terminals of an electric heater is 60V when it draws a current of 4A from the source what current will the heater draw if the potential difference is increased to 120V

Answer 1

Answer:

The potential difference between the terminals of an electric heater is 60 V when it draws a current of 4 A from the source. What current will the heater draw if the potential difference is increased to 120 V? We are given, potential difference V = 60 V, current I = 4 A. The current through the heater becomes 8 A.

Answer 2

Answer:

We are given, potential difference V = 60 V, current I = 4 A. <br> According to Ohm’s law,

<br> When the potential difference is increased to 120 V the current is given by <br> current =

<br> The current through the heater becomes 8 A.
