Well the calculator says 1.23457 watts in 18 ohms. o.o

OpenStudy (anonymous):

ohm is resistance watt is power power(watts) = Voltage x current = voltage (volts) squared/resistance (ohms)

OpenStudy (anonymous):

\[W=V \times I\]

Need more info. 18 ohms is just part of the problem. If we assume 120V, the V^2/18 = 800 watts, not a choice what voltage is assumed?

OpenStudy (anonymous):

If it's 12 Volts then 144/18=8.

Well if you put it in the equation then yes, yes it is.
