Quiz: Mutual Induction
Ans: The process of inducing a current flow through a secondary coil, by
passing a varying current on the primary coil
Quiz: Secondary Induced Voltage
Ans: Voltage induced in the secondary winding of a transformer is equal to the
sum of the voltages induced in each loop of the secondary winding.
Quiz: Eddy Currents
Ans: Loops of electrical current induced within conductors by a changing
magnetic field in the conductor due to Faraday's law of induction.
Quiz: Faraday's Law

, Ans: Is a basic law of electromagnetism predicting how a magnetic field will
interact with an electric circuit to produce an electromotive force (EMF)—a
phenomenon called electromagnetic induction. It is the fundamental operating
principle of transformers, inductors, and many types of electrical motors,
generators and solenoids.
Quiz: Delta-Connected Transformer
Ans: Delta-Connected Transformers have three transformer windings
connected end to end with each other. The line conductors are connected to
each point where two windings meet.
Quiz: The Delta High-Leg conductor is required to be terminated on the
_______ phase position in a meter socket enclosure?
a. A phase
b. B phase
c. C phase
d. Doesn't matter

, Ans: c. C phase
Quiz: Wye-Connected Transformer
Ans: Wye-Connected Transformers have one lead from each of the three
windings connected to a common point. The other leads from each of the
windings are connected to the line conductors.
Quiz: The turns ratio is defined as:
Ans: number of secondary windings divided by primary windings
Quiz: What's the primary voltage a transformer if the turns ratio is 10:1 and
the secondary voltage is 12V?
a. 24V
b. 1.2V
c. 120V
d. 12V
