Question

1. The potential difference between the
terminals of an electric heater is volt
when it draws a current of 4 Ampere
from a source. What current will the
heater draw if the Potential difference
is increased to 120 volto​

Answer 1

Answer:

V=60VI=4A

R=

I

V

=

4

60

=15Ω

When potential difference is increased to 120V

I=

R

V

=

15

120

=8A

The current through the heater becomes 8A
