What is joules heating law?????????

plz answer fast tomorrow exam


mood: The heat is produced ina conductor due to floe of current through it is proportional to the time of current flowing.when the electric resistance andthe amount of current is constant

hello

The heat which is produced due to the flow of current with in an electric wire is expressed in unit of joules.

hope this help u

thanku

HEYA....THERE!!!!

YOUR ANSWER IS.....

This experiment heat is produced by passing a current through a resistor which is immeresed in a container of water. The purpose of this experiment is to compare the energy dissipated by the resistor to that absorbed by the water thereby testing the principle of conservation of energy.

□When an object is heated, the transfer of energy Q to the object results in an increase in the object's temperature deltaT according to the relationship Q=mc(delta)T

■ where V is the potential difference across the resistor, and I is the current passing through the resistor After an amount of time t has elapsed, the energy E dissipated in the resistor is E =Pt=VIt.

□where m and c are the mass and specic heat of the object.1 When a potential difference is applied across a resistor, a current passes through the resistor resulting in the generation of heat (Joule heating).

■The rate at which the resistor dissipates the energy (the heat) P is P =VI where V is the potential difference across the resistor, and I is the current passing through the resistor After an amount of time t has elapsed, the energy E dissipated in the resistor is ..E = Pt = VIt.....
