Question

a electric bulb of resistance 44ohm draws a current of 5a calculate the voltage

Answer 1

Solution:

From the question,

Resistance:44Ω

Current:5A

Potential Difference:?

Let the Potential Difference be x.

From Ohm's Law,

Potential Difference= Current×Resistance

=>V=IR

=>x=(44)(5)

=>x=220V

The potential difference of the bulb is 220 volts

Answer 2

from the given condition

1.resistance 4 ohm

2. current 5A

by ohms law

R=I×V

R=5×44

=220 ohm
