Homework Answers
Heating produced of Electric Current is given by
.....................(1)
where I= current
R= resistance
t= time taken
then since temperature is not that much to change the resistance thus Resistance of the conductor will be constant. Then to measure the heating effect of electric current, we have to measure the electric current(using equation 1)
Hence correct option: d.current.
