Question:medium

A coil with "I" amperes of current and "R" ohm resistance and "t" is time in second, the heat produced 'H' in joules is given by which of the following equation ?

Show Hint

Joule heating is also known as "resistive heating" or "\( I^2 R \)" losses.
Because heat generation increases with the square of the current, doubling the current increases the heat produced by a factor of four.

H = I\(^{2}\)Rt
H = I\(^{2}\)R\(^{2}\)t
H = IR\(^{2}\)t
H = I\(^{2}\)R\(^{2}\)/t
