Please explain how to solve this!! What is the power dissipated by a toaster that has a resistance of 60 ohms and is plugged into a 120-V outlet? Show your work.
Answer: The correct answer is 240 W.
Explanation:
The expression for the power in terms of resistance and potential is as follows;
\(P=\frac{V^{2} }{R}\)
Here, V is the potential, P is the power and R is the resistance.
It is given in the problem that the toaster has a resistance of 60 ohms and is plugged into a 120-V outlet
Calculate the power dissipation.
\(P=\frac{V^{2} }{R}\)
Put V= 120 V and R= 60 ohms.
\(P=\frac{120^{2} }{60}\)
Therefore, the value of the power dissipation is 240 W.
