WebP = V * I. P = Power (watts) V = voltage (volts) I = current (amps) Looking back at our example of water flowing through a hose, we can now see how power is directly related to current and voltage using this equation. For example, imagine that you’re spraying the hose to turn a water wheel. The faster the wheel turns, the more power is generated. WebOct 31, 2000 · The voltage is equivalent to the water pressure, the current (amperage) is equivalent to the flow rate, and the resistance is like the pipe size. There is a basic equation in electrical engineering that states how the three terms relate. It says that the current is equal to the voltage divided by the resistance or I = V/R.

WebThe combination of reactive power and true power is called apparent power, and it is the product of a circuit’s voltage and current, without reference to phase angle. Apparent power is measured in the unit of Volt-Amps (VA) and is symbolized by the capital letter S. Calculating for Reactive, True, or Apparent Power WebThus, equation above tells us that electric power is voltage times current, or P = IV. This equation gives the electric power consumed by a circuit with a voltage drop of V and a current of I. For example, consider the circuit in Figure 19.24.
