115volts are how many watts?

Answer 1

That's like asking: How much time does it take to go 15 MPH? It depends on at least one other factor.

In your case, you cannot know watts unless you know voltage and current or resistance (from which you could derive current, because E = I x R).

Once you know the current drop across the 15 volts, you can multiply I x E and get P, i.e., amps times volts equals watts.

Answer 2

Voltage is a measure of electrical pressure. (Joules per coulomb) Watts is a measure of power rate. (Joules per second) The two are not related unless you also specify amps, which is a measure of current. (Coulombs per second) Watts equals Volts times Amps.

Answer 3

Watts and volts are different measures for different things. Watts = Volts x Ampers. This would be closest to an answer.

Answer 4

In order to calculate volts to watts one needs to know the amp and then 115 volts can be converted into watts.

Answer 5

115 x 10 amps =1150 watts
