Question

An electric bulb draws 1.5 A current at 7.5 V. Find the resistance of the filaments of bulb?

Answer 1

Resistance = voltage/current

So, by problem,

R = 7.5/1.5 = 5 ohm

Answer 2

HOLA!!

HERE YOUR ANSWER IS

GIVEN
current (I) = 1.5A

V = 7.5 V

SOLUTION

According to ohm's law

V/I =R

7.5 /1.5 =R

75/15 =R

Therefore R =5ohms

THE RESISTANCE OF THE FILAMENT OF THE BULB IS 5ohms

HOPE YOU UNDERSTAND!!!
