Question

45. Calculate the heat produced in a
wire of 10 ohm, carrying a current of
5 A for 2 minutes ? *​

Answer 1

Explanation:

Given :- Resistance = 2 Ω Current = 2.5 A. Time = 5 min. __________________________

To Find :- Heat Produced. ____________________

Solution :- 5 min = 5 × 60 = 300 s. We have formula :- _____________[Put Values] H = (2.5)² × 2 × 300. H = 6.25 × 2 × 300. H = 3750 J. H = 37.5 kJ.

Answer 2

Answer:

The heat generated in approximately equal to h=i^2*R*t.

Here I=5A

R=10ohm

t=60sec

so that h=25×10×60

=30000=30k Joules.
