watts / volts

[janeevans]

What is the equivalent in watts of a 240v light bulb.

[Gill1941]

think it is 100W

Have a look on a light bulb

[kempie]

There is no equivalent.

Light bulbs of different wattage (power) draw different currents from a set voltage i.e. a 100W bulb draws more current than a 60W bulb and is therefore brighter.

This is an unanswerable question.

Power = Voltage multip[lied by Current.

If you know two of these you can calculate the third.

A 240v lamp usually has the wattage stamped on the glass, 40W, 60W, 100W etc. Depending on the wattage rating a higher current will flow through a higher wattage lamp.

eg. a 100W lamp takes approx 0.4 amp

      a 60W lamp takes approx 0.25 amp
