Question

When a current of 0.5 A passes through a conductor for 5 min and the resistance of conductor is 10 W, find the amount of heat produced.​

Answer 1

Explanation:

I=0.5A

R =10ohm

t=5min (300second)

H=I^2Rt

H=750j

Answer 2

Answer: 750 J

Explanation:

So, according to the question,

Current = 0.5A = 5/10 A

Resistance of the conductor = 10 Ω (You had given the value in Watts here, but the correct unit is Ohms)

Time = 5 minutes = 5*60 seconds

As we know, Heat produced = I²RT

(Putting the values from the question)

$\frac{5}{10}$ * $\frac{5}{10}$ * 10 * 5 * 60

After calculation, the value comes out to be 750 Joules
