$IR^2$

Vedclass · Answer

(D) Electrical power is given by the expression,$P = VI$ $(i)$.According to Ohm's law,$V = IR$ $(ii)$.Where,$V =$ Potential difference$I =$ Current$R =$ ResistanceFrom equation $(i)$,substituting $V = IR$,we get:$P = (IR) 	imes I = I^2R$.From equation $(ii)$,substituting $I = \frac{V}{R}$,we get:$P = V 	imes \frac{V}{R} = \frac{V^2}{R}$.Therefore,the expressions for power are $P = VI = I^2R = \frac{V^2}{R}$.The term $IR^2$ does not represent electrical power.

$I$ (amperes)	$0.5$	$1.0$	$2.0$	$3.0$	$4.0$
$V$ (volts)	$1.6$	$3.4$	$6.7$	$10.2$	$13.2$

Which of the following terms does not represent electrical power in a circuit?
