Q
Q: What is the power consumed in an AC circuit with a voltage of 230V and a current of 5A with a power factor of 0.8? (2023)
Solution:
Power = V × I × Power Factor = 230V × 5A × 0.8 = 920W.
Steps: 7
Show Steps
Step 1: Identify the voltage in the circuit, which is 230V.
Step 2: Identify the current in the circuit, which is 5A.
Step 3: Identify the power factor, which is 0.8.
Step 4: Use the formula for power in an AC circuit: Power = Voltage × Current × Power Factor.
Step 5: Substitute the values into the formula: Power = 230V × 5A × 0.8.
Step 6: Calculate the result: 230 × 5 = 1150, then 1150 × 0.8 = 920.
Step 7: The power consumed in the circuit is 920W.
