Q1. Explain how a transformer’s turns ratio determines the secondary voltage,
and calculate the secondary voltage when the primary is 480 VAC with 300
primary turns and 125 secondary turns. [Short Answer]
Answer: The secondary voltage scales with the turns ratio: Vs = Vp × (Ns/Np). With Vp =
480 VAC, Ns = 125 and Np = 300, Vs = 480 × (125/300) = 200 VAC.
Explanation: This checks understanding of how a transformer’s turns ratio determines output
voltage. A correct answer states the proportional relationship (secondary voltage equals primary
voltage multiplied by the ratio of secondary turns to primary turns) and then applies those
numbers to compute 200 VAC, showing both concept and calculation.
Q2. Which of the following is NOT a component of a basic electrical circuit?
[Multiple Choice]
A) Insulator
B) Resistor
C) Conductor
D) Source
Answer: Insulator
Explanation: A basic electrical circuit requires conductive paths and components that allow
current flow (such as conductors, resistors, loads, and power sources). An insulator prevents
current flow and is therefore not a functional component in the conductive path of a basic circuit.
Resistor, conductor, and source are all typical parts of a circuit.
Q3. Rotary motion is the output of which electrical output device? [Multiple Choice]
A) Motor
B) Generator
C) Transformer
D) Solenoid
Answer: Motor
Explanation: A motor converts electrical energy into mechanical energy that typically produces
rotary (rotational) motion. A generator converts mechanical energy into electrical energy
2
, (opposite function). A transformer transfers energy between circuits by mutual inductance but
does not produce rotary motion. A solenoid can produce linear motion (push/pull), not rotary
motion.
Q4. What is the thin insulating material placed between the plates of a capacitor
called? [Multiple Choice]
A) Dielectric
B) Separator
C) Electrode
D) Farad
Answer: Dielectric
Explanation: The thin insulating material placed between the plates of a capacitor is called the
dielectric; it increases the capacitor's ability to store charge by reducing the electric field for a
given charge. 'Separator' is a generic term but not the technical name. 'Electrode' refers to the
conductive plates themselves, not the insulator. 'Farad' is the unit of capacitance, not the
insulating material.
Q5. What is the term for the potential difference between two points in an
electrical circuit? [Multiple Choice]
A) Voltage
B) Current
C) Resistance
D) Power
Answer: Voltage
Explanation: The potential difference between two points — the energy per unit charge that
drives current — is called voltage. Current is the flow of charge, resistance opposes current, and
power is the rate at which energy is transferred; none of those terms specifically mean the
potential difference between two points.
Q6. A common application of mutual inductance is found in which device?
[Multiple Choice]
A) Transformer
B) Inductor
C) Motor
3
, D) Capacitor
Answer: Transformer
Explanation: Mutual inductance — the induction of voltage in one coil by the changing current in
another nearby coil — is the operating principle behind transformers, which transfer energy
between circuits. An inductor is a single coil and can store energy; a motor uses electromagnetic
forces to produce motion; a capacitor stores energy in an electric field. None of those primarily
implement mutual inductance between two coils the way a transformer does.
Q7. On a sine wave graph, what does the unit 'hertz' represent? [Multiple Choice]
A) Cycles per second
B) Seconds per cycle
C) Waves per meter
D) Voltage per cycle
Answer: Cycles per second
Explanation: Hertz (Hz) is the unit of frequency and denotes the number of complete cycles that
occur each second. 'Seconds per cycle' would be the period (the reciprocal of frequency). 'Waves
per meter' relates to wavelength and spatial frequency, not temporal frequency. 'Voltage per
cycle' is not a standard definition of hertz.
Q8. What name is given to a drawing that uses electrical symbols to show
components and paths? [Multiple Choice]
A) Schematic
B) Diagram
C) Blueprint
D) Wiring list
Answer: Schematic
Explanation: A schematic is a drawing that uses standardized electrical symbols to show
components and the paths between them; it communicates how a circuit is connected. 'Diagram'
is generic and could mean many kinds of drawings; 'blueprint' is usually for mechanical or
architectural plans; 'wiring list' is a tabular inventory rather than a symbolic drawing. 'Schematic'
specifically denotes the symbolic electrical drawing.
Q9. Given a transformer with a 480 VAC primary of 300 turns and a secondary of
125 turns, what is the secondary voltage? [Multiple Choice]
