Question

An electric iron of resistance 20 ohm draws a current of 5 amperes. Calculate the heat produced in 30 seconds.​

Answer 1

given ;

r = 20ohms

I = 5A

t = 30

H = ?

solution ;

H = I²Rt

H = (5)²× 20 × 30

H = 25 × 600

H = 15000

hope it helps you..............

Answer 2

Answer:

Heat, H=I^2RT

I = 5 ampere

R = 20 ohm

T = 30 sec

H = 5^2×20×30

H = 15000 joules
