FormulaThe formula used by this calculator to determine the DC electrical power generated from the voltage and current is:P = V · ISymbolsP = Electrical power (DC) V = Voltage (DC) I = Current (DC)Voltage (V)This is the DC voltage or electrical potential difference applied to or ...
Power Factor Formula: The power factor is calculated as the cosine of the phase angle between the source voltage and current. What is Power Factor? In electrical engineering, the power factor (PF) of an AC electrical power system is defined as the ratio of working power (measured in kilowatt...
The electrical power at any given time is given by the current and voltage of the circuit. What is the electrical power formula? The electrical power is described in terms of the current (I) and voltage (V) of the system by the following formula: P = I × V In AC circuits, the ...
The basic equation to solve for power (P) when voltage (E) and current (I) are known is:P = E x Iwhere:P is the power in watts (W) E is the voltage in volts (V) I is the current in amperes (A)How to SolveTo determine the power using this formula, you multiply the ...
electric power can also be calculated using the electric current and voltage. Therefore, electric power is given by the formula: {eq}P=V \times I {/eq} where {eq}V {/eq} is the voltage measured in volts (V), and {eq}I {/eq} is the electric current measured inAmperes(A). Electr...
