Answer to Question #105953 in Electricity and Magnetism for leo

Question

An iron has a power of 1000 W. How much energy will it electrically transfer each second?

Answer 1

Power is the rate of doing work or of transferring heat per unit of time, or, in other words, power is the rate of transferred energy per unit of time

$$P=\frac{E}{t}$$

$P$ - power

$E$ - transferred energy

$t$ - time it took to tranfer energy $E$

In our case, $P=1000 W, t=1s \rArr E=Pt=1000*1=1000 J$
