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

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.

R = V/I = 120 / 4.6 ≈ 26 ohms.

Option C.
