state joules law of heating write the mathematical formula
Answers
Answer:
The law says that heat produced in a resistor is:-
1) directly proportional to the square of current for a given resistance.
2) directly proportional to the resistance.
3) directly proportional to the time for which current flows through the resistors.
It's mathematical formula is :-
H= I2RT
Explanation:
the law implies that heat produced in a resistor is
1) directly proportional to the square of current for a given resistance
2) directly proportional to resistance for a given current
3) directly proportional to the time for which the current flows through the resistor.
methametical formula
heat energy due to current=electric power X time
H=P X T
H=VI X T
H= VIT
also putting v = IR by ohms law
H=VIt
H= (IR) X It
H=I square x R X t
