A 500-W toaster is plugged into a 120-V AC outlet.What is the peak current in the toaster?
A)0.24 A
B)4.2 A
C)2.9 A
D)0.34 A
E)5.9 A

We can use the equation P = VI to calculate the current in the toaster.

P = 500 W (given)
V = 120 V (given)

Solving for I, we get:

I = P/V = 500/120 = 4.17 A

However, this is only the RMS (root mean square) current. To find the peak current, we need to multiply by the square root of 2:

I_peak = I_RMS x sqrt(2) = 4.17 x sqrt(2) = 5.9 A

Therefore, the peak current in the toaster is 5.9 A.
