Circuits: reactive,active, and power factor

[jhess1184]

I found total impedance to be 14.23 ohms with an angle of 20.15. Found power factor to be .938
Pretty much stuck at a dead end trying part 2 and 3.

[STRIKE]Can you detail your calculation of impedance and power factor? 14.24 Ohms seems a bit small to me.[/STRIKE]
EDIT: Never mind, my mistake: you have the impedance correct.

What's the magnitude of the voltage supply, E?

Supply voltage or current was not given. Just found out we were supposed to assume a 120v with angle 0 supply.

Okay, so you known the voltage supplied and you know the impedance. You should be able to find the power delivered.

I can provide some clarification on the concepts of reactive and active circuits, as well as power factor. In simple terms, a reactive circuit is one that contains components such as inductors and capacitors that store and release energy, causing a phase shift between voltage and current. An active circuit, on the other hand, includes components such as transistors or amplifiers that can manipulate the flow of electricity.

Based on the information provided, it seems that you have calculated the total impedance of a circuit to be 14.23 ohms with an angle of 20.15 degrees. This angle, also known as the phase angle, represents the phase shift between voltage and current in a reactive circuit. In this case, the phase angle suggests that the circuit contains both reactive and active components.

Additionally, you have found the power factor to be 0.938. Power factor is a measure of how efficiently a circuit uses electrical power. A power factor of 1 indicates that the circuit is using all of the supplied power, while a power factor less than 1 suggests that some power is being wasted due to reactive components. In this case, a power factor of 0.938 indicates that the circuit is using a majority of the supplied power, but there is still some room for improvement in efficiency.

As for the second and third parts of your inquiry, it would be helpful to have more context or specific questions to provide a more thorough response. However, I would suggest further exploring the components and calculations involved in determining power factor, as well as the implications of a high or low power factor in a circuit.
