Question

derive S.I unit of power

Answer 1

hie this may give u a clear view I think

Answer 2

S.I. unit of power is derived below -

• The formula of power = work/time. The S.I. unit of work is Joules and time is seconds.
• So, S.I. unit of power = Joules/seconds, which is equal to Watt.
• Now, 1 Watt will be defined as "the rate of consumption of energy in an electric circuit". The concerned electric circuit would have 1 Volt of potential difference and 1 Ampere of current.
