1. What are three types of inductors? - ANSWER air core, iron core,
variable
2. What happens once max current is reached in inductor - ANSWER
inductor no longer opposes current and acts like a short
3. What happens when AC voltage is applied to inductor - ANSWER
current is constantly changing and inductor constantly opposes current
4. What is inductance? - ANSWER ability of a conductor to induce voltage
when "cut" by magnetic flux
5. What is the basic unit of inductance? - ANSWER Henry
6. What factors affect inductance? - ANSWER Number of turns, distance
between windings, cross sectional area, permeability
, 7. More turns in inductor results in (higher/lower) inductance? - ANSWER
higher
8. Shorter inductor equals (more/less) flux density? - ANSWER more
9. Higher cross sectional area of inductor equals (higher/lower) inductance? -
ANSWER higher
10.What is inductive reactance? - ANSWER amount of opposition to
current flow

12.Voltage leads current by how many degrees in inductive circuit? - ANSWER
90
13.What does ELI stand for? - ANSWER Voltage leads current in inductive
circuit
14.What is impedance (Z) - ANSWER combined opposition to current flow
from resistor and inductor
