WebIn calculating the power in the circuit of Figure 19.21, we used the resistance and Ohm’s law to find the current. Ohm’s law gives the current: I = V / R, which we can insert into the equation for electric power to obtain. P = I V = ( V R) V = V 2 R. This gives the power in terms of only the voltage and the resistance. WebElectric Energy. Electrical Energy = Power x Time. The total amount of electrical energy used depends on the total power used by all your electrical devices and the total time they are used in your home. Electical Energy is measured in kilowatt-hours. Energy =Power x Time or Kilowatt-hours = Kilowatts x Hours. One kilowatt hour is equal to 1000 ...
What is Power Factor? How to Calculate Power Factor Formula
WebMathematically, it is computed using the following equation. Power = Work / time. or. P = W / t. The standard metric unit of power is the Watt. As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time. Thus, a Watt is equivalent to a Joule/second.
