# How many 100 watt light bulbs can run on a 15 amps circuit at once without blowing the fuse

[From: ] [author: ] [Date: 11-12-18] [Hit: ]
8333 Amps.15 / 0.08333 = 18.So a 15 Amp circuit can power 18 100 Watt lights bulbs.If you are in the USA then V = 115V,3600/100 = 36 bulbs depending on the fuse (p.......
I know the formula is:

Power= Current x Voltage

Thanks for the help!

You have you answer if you're in the U.K. In North America, the answer would be:

P = 100 Watts
E = 120 Volts
I = 0.8333 Amps per bulb
R = 144 Ohms resistance.

So a 100 Watt bulb on 120 Volts uses 0.8333 Amps.

15 / 0.08333 = 18.

So a 15 Amp circuit can power 18 100 Watt lights bulbs.

Assuming you are in the UK where V = 240V
then total wattage using 15A will be
W = 240 x 15
W = 3600 Watts

Since each bulb uses 100 watts then the number of bulbs = 3600/100 = 36

If you are in the USA then V = 115V, in this case W = 115 x 15 = 1750 Watts
Number of bulbs = 17

It depends on the ampage limit on the fuse whether its 3A or 13A

W = 240 x 15
W = 3600 Watts
100W bulb
3600/100 = 36 bulbs depending on the fuse (p.s for UK)
