Question 1.
What is self-inductance?
Show hintHide hint
Think about how changing current affects magnetic fields.
Question 2.
What unit is used to measure self-inductance?
Show hintHide hint
Recall the SI units of inductance.
3Question 3.
What does self-inductance measure?
- The induced emf of a coil
- The energy stored in an electric field
- The efficiency of a circuit
Show hintHide hint
Focus on the relationship between emf and current.
4Question 4.

- True
- False
Show hintHide hint
Think about how energy conservation plays a role.
Question 5.

Show hintHide hint
Consider how inductors behave in AC vs DC circuits.
Question 6.
Explain how self-inductance affects the transient response in a power supply circuit.
Show hintHide hint
Think about energy storage and gradual changes in current.
