Inductance Flashcards
1
Q
When does inductance occur?
A
When a length of wire is wrapped into a coil and the magnetic coil increases as the current flows.
2
Q
What is the phase shift of a purely inductive circuit?
A
90 degrees
3
Q
What type of circuit lags the waveform by 90 degrees?
A
A purely inductive circuit.
4
Q
What causes the lagging in an inductive circuit?
A
The time delay is caused by the induced emf on the foul opposing the supply emf
