General - AM.I.A.K4 - Inductance in a circuit Flashcards
1
Q
What is meant by inductance?
A
The ability to store electrical energy in electromagnetic fields
2
Q
What is the basic unit of inductance?
A
The henry
3
Q
Given the inductance and the frequency of the AC in a circuit, how do you compute the inductive reactance caused by the coil?
A
XL = 2pifL
Where XL = inductive reactance in ohms
f = frequency in cycles per second
pi = 3.1416
L = inductance
