Calculate the quantity of heat produced in a 20 Ω resistor carrying 2.5 A current in 5 minutes.
Given : R = 20Ω, I = 2.5 A
t = 5 minutes = 5 x 60 = 300 s
Quantity of heat produced is given as
H = I2Rt
= (2.5)2 x 20 x 300
∴ H = 37500 J
Concept: Concepts of Pd (V), Current (I), Resistance (R) and Charge (Q).
