Single Phase Power Calculator:
Enter the values of input voltages, V(V), current, I(A) and power factor, PF to determine the value of Single phase power, P-1(W).
Single Phase Power Formula:
Single phase power (P1) signifies the rate at which electrical energy is consumed or converted into other forms of energy in a single-phase AC electrical system. It is typically measured in watts (W).
This power reflects the amount of work done by the electrical energy in driving devices or loads connected to the system.
Higher voltage generally leads to higher power consumption if other factors remain constant. Higher current flow signifies more electrical energy flowing through the appliance per unit time, potentially leading to higher power consumption.
The electrical supply provides a voltage (V) that pushes a current (A) through the appliance. The appliance utilizes this electrical energy to perform its function (e.g., a heater converts it into heat, a motor converts it into mechanical work).
The power factor (PF) reflects how efficiently this conversion occurs.
Single phase power, P-1(W) in watts is calculated by the product of input voltages, V(V) in volts, current, I(A) in amperes and power factor, PF.
Single phase power, P-1(W) = V(V) * I(A) * PF
P-1(W) = single phase power in watts, W.
V(V) = voltage in volts, V.
I(A) = current in amperes, A.
PF = power factor.
Single Phase Power Calculation:
- An electrical device operates at 230 volts (V) and draws a current of 10 amperes (A) with a power factor of 0.8. Calculate the single-phase power consumed by the device.
Given: V(V) = 230V, I(A) = 10A, PF = 0.8.
Single phase power, P-1(W) = V(V) * I(A) * PF
P-1(W) = 230 * 10 * 0.8
P-1(W) = 1840W.
- An air conditioner operates at 120 volts (V) with a power factor of 0.9 and consumes 1080 watts (W) of power. Calculate the current drawn by the air conditioner.
Given: V(V) = 120V, P-1(W) = 1840W, PF = 0.9.
Single phase power, P-1(W) = V(V) * I(A) * PF
I(A) = P-1(W) / V(V) * PF
I(A) = 1840 / 120 * 0.9
I(A) = 10A.
