Question

guys please help me with this question and whoever will give me the answer I will mark them as brainlist but I don't want any useless answers​

Answer 1

Explanation:

Given, I = 3 A

V = 12 Volts

(i) Using Ohm's law :

V = I R, where R is the resistance of the filament.

So, R = V/I = 12/3 = 4 ohms

(ii) Since, P = I2 R

So, power of the lamp, P = (3)2 X 4 = 36 Watt
