Question

calculate the heat generated while transfering 72000c of charge in 45 minutes through potential difference 50 volt.​

Answer 1

HEAT GENERATED = $I^{2}$VT

WE KNOW THAT I=Q/T

Q=72000c

T=45 minutes or 2700sec

V=50 volt

                           so therefore heat is=$(72000/2700)^{2}$×VT

                                                           =26.66×50×2700=36,00,000 joules
