Power to Current Calculator
Enter the values of power, P(W) and voltage, V(V) to determine the value of Current, I(A).
Power to Current Formula:
Power to current conversion is a fundamental concept in electrical engineering that involves determining the amount of current (I) flowing in a circuit, given the power (P) being used and the voltage (V) across the circuit.
In AC circuits, both the voltage and current are often referred to in terms of their RMS values, which represent the effective value of a sinusoidal voltage or current, equivalent to a DC value delivering the same power.
The power factor is crucial in AC circuits because it impacts the phase angle between the current and voltage, thereby affecting the actual power (true power) used in the circuit.
The conversion from power to current depends significantly on the type of current (AC or DC), the power factor, and the system’s phase.
Current, I(A) in amperes is calculated by dividing the power, P(W) in watts by voltage, V(V) in volts.
Current, I(A) = P(W) / V(V)
I(A) = current in amperes, A.
P(W) = power in watts,W.
V(V) = voltage in volts, V.
Power to Current Calculation:
- Calculate the current for a circuit consuming 1000 watts of power at a voltage of 220 volts:
Given: P(W) = 1000W, V(V) = 220V.
Current, I(A) = P(W) / V(V)
I(A) = 1000 / 220
I(A) = 4.55A.
- If a device draws a current of 2 amperes at a voltage of 12 volts, calculate the power consumption:
Given: I(A) = 2A, V(V) = 12V.
Current, I(A) = P(W) / V(V)
P(W) = I(A) * V(V)
P(W) = 2 * 12
P(W) = 24W.
