## Toaster Oven Resistor

Consider a 30 V toaster oven consumes 300 W of power. What ohm resistor is it installed with?

Hint
Power absorbed by a resistive element:
$$P=VI=\frac{V^{2}}{R}=I^2R$$$where $$V$$ is voltage, $$I$$ is current, and $$R$$ is resistance. Hint 2 Based on the problem statement’s givens, solve for resistance using the equation: $$P=\frac{V^{2}}{R}$$$

$$R=\frac{900}{300}=3\:\Omega$$\$
