Inductor (L) - (ANSWER)A device that opposes a change in current
Inductance (L) - (ANSWER)The characteristic of an electrical conductor which opposes a CHANGE in
current flow The measure of a coils ability to oppose a change in current, measured in henrys
Inductive Reactance (Xl) - (ANSWER)The opposition to the flow of alternating current caused by the
inductance of a circuit, measured in ohms
Impedance (Z) - (ANSWER)The total opposition to current flow in an AC circuit. It is the vector sum of
resistance and reactance, measured in ohms.
Henry (h) - (ANSWER)The unit of measure for inductance
Formula for Real Power (P) - (ANSWER)V x I x cos (-) = Watts
Formula for Reactive Power (Q) - (ANSWER)V x I x sin (-)= VARS
Apparent Power (S) - (ANSWER)V x I = VA
Formula for Power Factor (PF) - (ANSWER)cos (-)
What determines the strength of a magnetic field? - (ANSWER)1. The number of turns in the coil
2. The material of the conductor
3. The amount of current flow through the conductor
