1. • Power multiplied by Time, (V*I*t joules)

     • So if 1 watt = 1 joule per second, it therefore follows that: 1 Joule of energy = 1 watt over one unit of time, that is: Work equals Power multiplied by Time, (V*I*t joules). So electrical energy (the work done) is obtained by multiplying power by the time in seconds that the charge (in the form of a current) flows.

   How do you calculate electrical energy?

   • Electrical energy is the product of power multiplied by the length of time it was consumed. So if we know how much power, in Watts is being consumed and the time, in seconds for which it is used, we can find the total energy used in watt-seconds. In other words, Energy = power x time and Power = voltage x current.

   How do you calculate power?

   • That is expressed as Power. Power = Electric potential x Current, or P = E x I. This formula makes the point that the power depends on both the amount of electricity being delivered and how much force there is behind it. For example, a small solar panel might produce 18 volts and 2 amps. Its power production would be 18 volts x 2 amps = 36 watts.

   How do you calculate electric potential?

   • Electric potential = Current x Resistance. This is Ohm's law and is usually written as: E = I x R. E is electric potential measured in volts, I is current measured in amps, and R is resistance measured in ohms. The electrons flowing through the resistance of a wire are doing work. Two kinds of work performed by the current are really useful.

   Then by using Ohm’s law and substituting for the values of V, I and R the formula for electrical power can be found as: To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps) Also: [ P = V2 ÷ R ] P (watts) = V2 (volts) ÷ R (Ω) Also: [ P = I2 x R ] P (watts) = I2 (amps) x R (Ω)
