What is primary winding?
the coil of wire that receives electrical power from the source. It is connected to the input voltage source.
another coil of wire, usually wound around the same iron core as the primary winding but electrically isolated from it.
winding that first
winding that second
Secondary winding is...
the coil of wire that receives electrical power from the source. It is connected to the input voltage source.
another coil of wire, usually wound around the same iron core as the primary winding but electrically isolated from it.
winding that first
winding that second
Defined turns ratio, (n)
the sum of the number of turns in the primary winding (NP) to the number of turns in the secondary winding (NS)
the ratio of the number of turns in the primary winding (NP) to the number of turns in the secondary winding (NS)
the ratio of the number of turns in the primary winding (NS) to the number of turns in the secondary winding (NP)
the sum of the number of turns in the primary winding (NS) to the number of turns in the secondary winding (NP)
What is the formula for ratio, (n)?
VP/NS
NP/NS
Log N/Log 2
NS/NP
VP/VS
What is the true statement for this?
The primary and secondary voltages are in phase when the windings are in the same effective direction around the magnetic path.
The primary and secondary voltages are 180° out of phase when the windings are in the opposite direction.
Phase dots indicate relative polarities of primary and secondary voltages.
Which one is the voltages OUT of phase?
