Question

Rate of heat generated by electrical current in resistive circuit is expressed in:-
1) IR
2)IR^2
3)I^2R
4)under root 12​

Answer 1

Answer:

Calculating Resistive Heating

Power is measured in units of watts (W), which correspond to amperes x volts. Thus, a current of one ampere flowing through a resistor across a voltage drop of one volt produces one watt of heat. Units of watts can also be expressed as joules per second..

Answer 2

Answer:

correct answer is :

$\huge {H\:=\:I^2Rt} \:$
