takes current of 5 Ampere. calculate
the heat developed is 30 seconds.​

Answer 1

Answer:

An electric iron of resistance 20 ohm takes a current of 5A. calculate the heat developed in 30 seconds Get the answers you need, now! ... h = {5} ^{2} \times 20 \times 30 = hope it help you. 4.4.

Answer 2

Explanation:

H = I^2Rt

H=5^2×20×30

H=25×600

H= 1500 J

OR

heat genearated = 1.5 kJ
