2 cards from this section. Quick, good the night before a test.
What does self-induction refer to?
Think about how coils behave in changing electrical currents.
What is the unit of self-inductance?
Recall the name of the scientist associated with the unit.
What does self-induction describe?
Consider what happens when you try to change the flow of current in a coil.
Self-inductance is measured in which unit?
Remember the name associated with this unit.
A coil with a self-inductance of 5 H has a current that increases from 1 A to 6 A in 4 seconds. Calculate the induced emf.
Remember the formula and the rate of change of current.
Describe the effects of self-induction when an AC supply is connected to an inductor. How does this influence the circuit behavior?
Think about the relationship between AC and inductors in terms of phase.
