Question

What will the resistance be for a lamp that draws 4.6 amps of current from a 120-volt outlet? A. 550 ohms B. 115 ohms C. 26 ohms D. 0.038 ohms E. 5.7 ohms

Answer 1

To answer the question above, use the equation,
                                    V = I x R
where V is the potential difference or voltage, I is current, and R is the resistance. Substituting the known values,
                                  120 V = (4.6 amps) x R
The value of R is 26.09 ohms. Therefore, the answer is letter C. 

Answer 2

R = V/I = 120 / 4.6 ≈ 26 ohms.

Option C.
