Question

A 9V battery is connected to two light bulbs. If the current through the circuit is 1.5 A, what is the resistance of each light bulb (assume both light bulbs are identical)?

Answer 1

3 ohm

Step-by-step explanation:

Given :

V=9V

And according to given question same current is flowing in both resistance that means resistance will connected in series

So,

R= R+R=2R

Now,

Applying ohm's law

`V=IR\\9=1.5*2R\\9=3R\\R=(9)/(3) \\R= 3ohm`

Therefore, answer is 3 ohm
