Engineering How Do You Calculate Apparent and Reactive Power in AC Circuits?

Click For Summary
The discussion focuses on calculating apparent and reactive power in an AC circuit with a power factor of 0.72 lagging and a true power of 375 W. The apparent power is calculated to be approximately 520.83 VA, while the reactive power is found to be around 361.44 VAR. The magnitude of the current flowing in the circuit is determined to be 4.34 A, and the impedance is calculated as a complex value, indicating the circuit is inductive. Participants also discuss the importance of understanding complex numbers for accurate impedance calculations, emphasizing the need for proper arithmetic with real and imaginary components. Overall, the calculations and concepts presented are validated and refined through collaborative input.

Yes, that will work.

Is it correct to assume that the current value is the same throughout the circuit ? or would you obtain different value i.e. across the resistor

It is a series circuit, so there's no option: The current must be identical throughout.
