# Problem: Consider a 120 V AC microwave oven that draws 12.5 A.(Randomized Variables I = 12.5 A)What is the maximum instantaneous power consumption, in kilowatts, of the microwave?

###### FREE Expert Solution

Maximum instantaneous power:

$\overline{){{\mathbf{P}}}_{\mathbf{m}\mathbf{a}\mathbf{x}}{\mathbf{=}}{{\mathbf{i}}}_{\mathbf{m}\mathbf{a}\mathbf{x}}{{\mathbf{V}}}_{\mathbf{m}\mathbf{a}\mathbf{x}}}$

imax and Vmax

$\overline{){{\mathbf{i}}}_{\mathbf{m}\mathbf{a}\mathbf{x}}{\mathbf{=}}\sqrt{\mathbf{2}}{{\mathbf{i}}}_{\mathbf{r}\mathbf{m}\mathbf{s}}\phantom{\rule{0ex}{0ex}}{{\mathbf{V}}}_{\mathbf{m}\mathbf{a}\mathbf{x}}{\mathbf{=}}\sqrt{\mathbf{2}}{{\mathbf{V}}}_{\mathbf{r}\mathbf{m}\mathbf{s}}}$
