Question

.

Answer 1

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

Answer 2

ohm is resistance
watt is power

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

Answer 3

\[W=V \times I\]

Answer 4

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?

Answer 5

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

Answer 6

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

Answer 7

Well how about you give us our options?
