Question

The potential difference between the terminals of an electric heater is 250 V, when it draws a current
of 10 A. What current will the heater draw, if the potential difference is increased to 300 V?​

Answer 1

HELLO !! ✌✌

When Potential Difference,V =250V, current I=10A,

By Ohm's Law

Resistance R=V/I

=250/10

=25

When the potential difference is increased to 300V,  

the current drawn by the heater will be

I=V/R

=300/25

=12A

hope this helps u ↑↑
