A single-phase 230 V, 1 kW load is connected across single-phase 230 ...




Calculation of Power Delivered to the Load and Input Power Factor:




Given Parameters:
- Single-phase 230 V, 1 kW load connected across single-phase 230 V, 50 Hz supply through a diode




Calculation of Power Delivered to the Load:
- Power delivered to the load = 1 kW (given)
- Power factor (for resistive load) = 1
- Therefore, power delivered to the load = 1 kW




Calculation of Input Power Factor:
- Power input = Power delivered to the load = 1 kW
- Voltage = 230 V
- Current flowing through the circuit can be calculated using the formula: P = V x I x cos(θ) where θ is the phase angle between voltage and current
- Since the load is resistive, cos(θ) = 1
- Therefore, current = 1 kW / 230 V = 4.35 A
- Input power factor = cos(θ) = P / (V x I) = 1 / (230 V x 4.35 A) = 0.707




Final Results:
- Power delivered to the load = 1 kW = 1000 W
- Input power factor = 0.707
