A531.7-w space heater is designed for operation in germany, where household electrical outlets supply 230 v (rms) service. what is the power output of the heater when plugged into a 120-v (rms) electrical outlet in a house in the united states? ignore the effects of temperature on the heater's resistance.

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.
