Question

How to calculate the power of electricity from P=W/t

Answer 1

P= W/t

Power= work / time

You take the work number which ends with the unit joules and then divide by time which unit is seconds

So for example

IA machine does 40J of work in 5 seconds. How much power is that?

40/5= 20 Watts

Answer 2

One joule also equals the energy required to move an electric charge of one coulomb through an electric potential difference of one volt (J = C · V). Power (P) is the rate at which energy is transferred or converted. Thus, power equals work divided by time (P = W / t).
