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. 

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
