A current of 2 A, passing through a conductor produces 80

Home » Electricity and Magnetism » Current Electricity » Question

A current of 2 A, passing through a conductor produces 80 J of heat in 10 seconds. The resistance of the conductor in ohm is

1. 0.5
2. 2
3. 4
4. 20

Correct Option: B

H = I²RT

or R =	H	=	80	= 2 Ω
	(I²t)		(2² x 10)
