If a current of $1 A$ $1 A$ passing through a circuit generates $2 W$ $2 W$ of power, what is the resistance of the circuit?

$2$ $2$ ohms

Explanation:

For $R =$ $R =$ resistance (in Ohms)
and $I =$ $I=$ current (in Amperes)
and $P =$ $P =$ power (in Watts)

$P = R \times I^{2} \to R = \frac{P}{I^{2}}$ $P=RxxI^2 rarr R=P/(I^2)$

Given
$XXX P = 2 W$ $color(white)("XXX")P=2W$
and
$XXX I = 1 A$ $color(white)("XXX")I=1A$

$R = \frac{2}{1^{2}}$ $R=2/1^2$ Ohms $= 2$ $=2$ Ohms
