Question

The current drawn by an electric heater coil is 2A from 220V source. calculate it's resistance. If it draws 1A current find the potential difference of the circuit​

Answer 1

Explanation:

1.7 A

Ohm's Law, V=IR

Therefore, R=

V

I

So, R=

3.4

220

=64.7Ω

Now,

V=110 volt and R=64.7Ω

Hence, I=

R

V

=

64.7

110

=1.69 A
