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):
\[W=V \times I\]
OpenStudy (anonymous):
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.
