Question

A popcorn popper is rated at 0.60 kW when connected to a 120 V source. What current (in A) does the popcorn popper carry? and What is its resistance (in Ω)?

Expert Solution

Step 1

The current (I) can be calculated using Ohm's law: I = V / R, where V is the voltage and R is the resistance.

In this case, V = 120 V. So, we can calculate the resistance (R) as follows:

P = IV, where P is the power, so we have 0.60 kW = I * 120 V

I = 0.60 kW / 120 V = 5 A
