Question 1.
Define inductive reactance.
Show hintHide hint
Think about how inductors react to changes in AC current.
Question 2.
What is the phase difference between current and voltage in an inductor?
Show hintHide hint
Recall the relationship between voltage and current in AC circuits.
3Question 3.
What is the formula for inductive reactance?
- X_L = R
- X_L = ωL
- X_L = 1/(ωC)
Show hintHide hint
Recall the definition of inductive reactance.
4Question 4.
True or False: The average power dissipated in a pure inductor is zero.
- True
- False
Show hintHide hint
Reflect on the nature of how inductors store energy.
Question 5.
An inductive circuit has a frequency of 60Hz and an inductance of 150mH. Determine the current when a voltage of 120V is applied.
Show hintHide hint
Break down the calculation into reactance first, then current.
Question 6.
Explain the significance of a zero power factor in ac circuits with inductors, and how this understanding applies in circuit design.
Show hintHide hint
Think about energy storage versus energy dissipation.
