CORRECT ACTUAL QUESTIONS AND
CORRECTLY WELL DEFINED ANSWERS
LATEST ALREADY GRADED A+
operation of a transformer - ANSWERS-A transformer is an
electrical device that is used to transfer electrical energy
from one circuit to another through inductively coupled
conductors, or coils. It works on the principle of
electromagnetic induction, where a changing magnetic field
in one coil generates a voltage in the other coil.
Transformer Output Voltage Formula - ANSWERS-V_out =
V_in * N_secondary / N_primary
N= turns of coil
how to troubleshoot a transformer with a dmm - ANSWERS-
1. First, make sure that the power is off and that all safety
precautions are followed.
,2. Set the DMM to measure DC voltage, and check the input
and output terminals of the transformer for any voltage. If
there is no voltage at the input terminals, but there is
voltage at the output terminals, it could indicate a shorted
primary coil or an open secondary coil.
3. Set the DMM to measure resistance, and check the
resistance of the primary and secondary coils. If the
resistance of the primary or secondary coil is much higher or
lower than expected, it could indicate a problem with the
coil.
4. Set the DMM to measure continuity, and check the
connections between the primary and secondary coils. If
there is no continuity between the coils, it could indicate a
broken wire or a loose connection.
size a transformer given the voltage and load of the circuit -
ANSWERS-
what is a switch - ANSWERS-The switch is a device that is
used to control the flow of electrical current in the circuit. It
can be used to turn the circuit on or off, allowing the load to
be powered or de-powered as needed.
