Question

An electric bulb draws 2.5A current at 10V. Find the resistance of the filament of bulb.

Answer 1

Answer:

R=V/I=10/2.5=4 ohm is the R of bulb.

Answer 2

Answer:

4ohm

Given :

V = 10 volt

I = 2.5 ampere

R = V/I => R = 10/2.5 = 100/25 = 4 ohm .

(V - volt , I - current , R - resistance)

Hope this helps .

Have a nice day !
