Question

) The potential difference between the terminals of an electric heater is 120V when it draws a current of 5A from the source. What current will the heater draw if the potential difference is increased to 220V. 2

Answer 1

Answer:

Current,I=9.16A

Explanation:

Potential difference,V=120V

Current,I=5A

By Ohm's Law

V=IR

So, R=V/I

R=120/5

R=24 ohm

When potential difference,V is increased to 120V.

the current draw by heater is:-

I=V/R

I=220/24

I=9.16A

Answer 2

Answer of your question is above.
