What is the formula for calculating the total power in a three-phase AC system?
Correct Answer: P = √3 * V * I * cos(φ)
- Step 1: Understand that a three-phase AC system has three wires carrying alternating current.
- Step 2: Know that 'P' represents the total power in watts.
- Step 3: Recognize that 'V' is the voltage across each phase in volts.
- Step 4: Identify 'I' as the current flowing through each phase in amperes.
- Step 5: Learn that 'cos(φ)' is the power factor, which accounts for the phase difference between voltage and current.
- Step 6: Combine these elements into the formula: P = √3 * V * I * cos(φ).
- Step 7: Use this formula to calculate the total power in a three-phase AC system.
