Question

How much heat be developed if 0.2a current flow through a conductor of 200 ohm resistance for 10 minutes

Answer 1

Explanation:

we know that,

h=i²*r*t

=(0.2)²*200*600

= 4800 joules

Bhai........

hope it is helpful......

Answer 2

it's ans

Heat can be find by formula

H = I square RT

I=0.2, R= 200ohm and time= 10 min (given that )

put all value

H=0.2× 0.2×200 ×600 second (10min=60 sec).

H= 4800J ( J is unit of heat )
