Question

potential difference of 240v is applied across the heating coil of an electric kettle driven by a current of 8A through the coil. Calculate the resistance of the coil
Options
A 3 Ohms
B 30 Ohms
Correct Answer
C 1920 Ohms
D 19.2 Ohms
Correct Answer

Option B is the correct answer.

Detailed Explanation

R = V/I = 240 V / 8 A = 30 Ω.

Hint

Ohm's law: R = V/I.
