Question

The potential difference between the terminals of an electric heater
is 45V when it draws a current of 3A from the source. What current
will the heater draw if the potential difference is increased to 90V?

Answer 1

Answer:

we know V= IR

45 = 3 × R

R= 15 ohms

next situation.........

R will be same so

90=I× 15

I = 6 A
