Через спираль электрической плитки за 10 минут прошел электрический заряд,равный 1200 Кл. Какова мощность плитки,если напряжение в сети 220В?

Answers & Comments

kirills1 $P = U * I = U * \frac{q}{t} = \frac{Uq}{t}$

U - напряжения ( 220 В )
q - заряд ( 1200 Кл )
t - время ( 10 мин = 600 с )

$P = \frac{220*1200}{600} = \frac{264000}{600}$ = 440 Вт
