What is the resistance of a toaster that uses 2 A of current when connected to a 120-volt power source?

Question

A) 240 ohms

B) 120 ohms

C) 60 ohms

D) 2 ohms

E) None of the above

Can you please explain your answer

Answer 1

You've learned Ohm's Law, right?  E=IR.

Solve for R.

R=E/I.

Divide the voltage (in volts) by the current (in amperes) and you get the ohms.
