Question

state and derive joules law of heating . calculate amount of heat generated when 18000c of charge is transferred in one hour through potential difference of 50v?​

Answer 1

Answer:

Joules law of heating=H=I*2RT

joules law if heating is

■directly proportional to the squareof the current passing through the resistor

■directly proportional to the resistance of the resistor

■directly proportional to the time through which the resistor is passing.

Answer 2

Answer:

Net charge(Q)=18000C

time taken(t)=1hour=3600sec

potential difference(V)=50v

H=I^2Rt

H=VQ/T

H=50×18000/3600

H=250Js^-1
