Single-Phase Calculator
Calculate single-phase electrical parameters including current, power, voltage, and resistance. Perfect for electrical engineering, home electrical projects, and industrial applications.
Step 1: Basic Parameters
Understanding Single-Phase Systems
Single-phase systems are commonly used in residential and light commercial applications. Typical voltage: 120V (US) or 230V (EU). Power factor ranges from 0.5 (poor) to 1.0 (excellent).
Step 2: Additional Parameters
Electrical Formulas
Power (P) = Voltage (V) × Current (I) × Power Factor (PF)
Apparent Power (S) = Voltage (V) × Current (I)
Reactive Power (Q) = √(S² – P²)
Resistance (R) = Voltage (V) / Current (I)

Single-Phase Power Formulas
Real Power (P) = V × I × cos φ (kW)
Apparent Power (S) = V × I (kVA)
Reactive Power (Q) = V × I × sin φ (kVAr)
Power Factor (PF) = cos φ = P / S
