JAMB - Physics (1983 - No. 23)
Of the following derived units, the one that is not a unit of power is
joule/second
ampere volt
ampere2volt
volts2/ohm
Penjelasan
Power = \(\frac{Work done}{time}\) = \(Js^{-1}\)
Power = \(current \times voltage\) = \(Ampere volt\)
Power = \(\frac{voltage^{2}}{resistance}\) = \(\frac{volts^{2}}{ohm}\)
