Answer:

Explanation:

On electrical devices there is a label often giving the power required to operate the device.

A typical incandescent bulb might be 60W meaning it draws 60W of power although little of this power is turned into light, most is converted to heat. A CFL draws less power, but can turn most of the power into light. One will see on CLF like 14W, but equivalent to 60W incandescent meaning the 14W CFL puts out the same amount of light as the 60W bulb. LEDs are even more efficient and draw less power.

A typical iron, clothes type, will draw about 1000–1400 W, which is much more than what would be the typical incandescent bulb used in a common home. Seldom does one see a bulb of 100W except in some spot light bulbs.

Since a bulb and the iron essentially convert much of the power they draw into heat this is done with heating elements with resistance.

As other said P=I^2 x R or P=E^2/R or P=V x I.

As can be seen the resistance will determine the power consumed by the iron and bulb.

Of course a bulb often remains on for longer periods of time than the iron so the total kWHr, what one pays for, the bulb will probably consume more power over time. But a typical iron will draw more power than the typical bulb.
