Question

What is the resistance of a filament lamp when a voltage of 3 V across it causes a current of 0.5 A?

Answer 1

Answer:

6Ω

Explanation:

Using ohms law,

V = IR

Where V is the voltage

            i is the current

and       R is resistance

V= 3v

i = 0.5A

R = ?

using ohms law , we have

3 = 0.5 × R

divide both side by 0.5

R = 3/0.5 = 6Ω

Answer 2

Answer:6ohm
