Question

When a current of 0.5 A passes through a conductor for 5 min and the resistance of conductor is 10 Ω, the amount of heat produced is:

(a) 250 J (b) 5000J

(c) 750J (d) 1000J
( this is a chemistry question )

Answer 1

Answer:

the anwer of this question is c

Step-by-step explanation:

I=0.5A

R =10ohm

t=5min (300second)

H=I^2Rt

H=750j

Answer 2

(c)750J (ANSWER)

⇒To calculate the amount of heat produced we will use the formula I²×R×T.

⇒I=Current passing through the conductor

⇒R=resistance of the conductor

⇒T=Time for which that amount of current passed through that conductor.

⇒The current value given in the question is 0.5A.

⇒The value of time is 5 mins which are equal to 5×60=300sec

⇒The value of resistance given in the question is =10 ohm

⇒so, the heat produced will be= I²×R×T

⇒0.5²×10×300=750J(ANSWER)
