An electric resistor of 20 ohms draws a current of 5a calculate the heat produced by its in 30 sec

Answer»

Solution:

GIVEN that Resistance(R) = 20 Ω, Electric current (I)= 5 A and time(t)= 30 s

Now we KNOW that H= I2Rt

                                = 5×5×20×30

                                = 15000J=1.5×104J

∴ The HEAT developed in 30S is 1.5×104J
