Homework Answers
ANSWER A:
Isolation transformers are used for isolation of conduction paths between primary and secondary windings to protect it from unnecessary current and DC component of signals. Hence the Answer is C .
ANSWER B:
As turns ratio is 4, which is equal to Primary Voltage / Secondary Voltage. So, the Secondary Voltage is Primary Voltage / Turns Ratio, which is equal to 480/4, that is 120 V. So, Answer is D.

Learning Goal: To understand the concepts explaining the operation of transformers.One of the advantages of alternating current (ac) over direct current (dc) is the ease with which voltage levels can be increased or decreased. Such a need is alwayspresent due to the practical requirements of energy distribution. On the one hand, the voltage supplied to the end users must be reasonably low for safety reasons(depending on the country, that voltage may be 110 volts, 220 volts, or some other value...

1 A single phase AC system Consider a single phase AC distribution system in which there a single home connected to a 10kVA service transformer. Let’s assume that the primary of the distribution transformer can be modeled as an ideal 240V (rms) AC source and that the effective impedance of the transformer is 2% resistance and 3% reactance. (See lecture notes for converting % to Ohms). Connected to the secondary of the transformer is 200 ft of #6 AWG aluminum...
