Calculate the quantity of heat that will be produced in a coil of resi

1.	Calculate the quantity of heat that will be produced in a coil of resistance 75Ω if a current of 2A is passed through it for 2 minutes.
Answer» Here, R = 75 Ω, i = 2A, t = 2 minutes = 2 × 60 = 120s Now, Heat produced H = i² Rt = 2 × 2 × 75 × 120J = 36000J

Calculate the quantity of heat that will be produced in a coil of resistance 75Ω if a current of 2A is passed through it for 2 minutes.

Answer»

Here, R = 75 Ω,

i = 2A,

t = 2 minutes = 2 × 60 = 120s

Now, Heat produced

H = i² Rt

= 2 × 2 × 75 × 120J = 36000J
