Question Description
I don’t know how to handle this question and need guidance.
XL
- Explain briefly why XL limits the amount of alternating current.
- Explain why XL increases with higher frequencies and more inductance. How might you use this fact in an application.
Inductive Circuits
- What characteristic of the current in an inductance determines the amount of induced voltage? State briefly why.
- Why is the voltage across a resistance in phase with the current through the resistance?
RC and L/R Time Constants
- Give an application in electronic circuits for an RC circuit with a long time constant and with a short time constant.
- Discuss why an arcing voltage could be a problem with coils used in switching circuits.
Power
- Compare real power and apparent power.
- Define power factor and discuss the topic of power factor correction.
