Sample Odisha CHSE +2 VOC-ITV Wireman Control Panel Practice Questions

Try these sample questions to test your Odisha CHSE +2 VOC-ITV Wireman Control Panel exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1According to Ohm’s law, the voltage (V) across a conductor equals:
A.Current plus resistance (V = I + R)
B.Current divided by resistance (V = I / R)
C.Current times resistance (V = I × R)
D.Resistance divided by current (V = R / I)
Explanation: Ohm’s law states V = I × R for a conductor at constant temperature. Wireman control-panel technicians use it to interpret meter readings and estimate loads.
2In a simple series circuit, the same value of which quantity flows through each component?
A.Voltage drop
B.Current
C.Resistance
D.Power
Explanation: In series, there is one path, so the same current flows through every series component. Voltage divides across resistances according to their values.
3On a standard single-phase power socket, the three conductors are commonly identified as:
A.Phase only, shield, and chassis paint
B.Live (phase), Neutral, and Earth
C.Positive DC, Negative DC, and Signal
D.Hot, cold, and refrigerant return
Explanation: Domestic/industrial single-phase sockets provide Live (phase), Neutral, and protective Earth. Identifying L, N, and E correctly is a core Class 11 practical outcome.
4Kirchhoff’s Current Law (KCL) states that at a circuit node:
A.Voltage is always zero regardless of load
B.The algebraic sum of currents entering and leaving is zero
C.Resistance must equal inductance
D.Power is conserved only in open circuits
Explanation: KCL is charge conservation: currents into a node equal currents out (algebraic sum zero). Panel fault-finding often starts by checking unexpected current paths at junctions.
5Which statement correctly contrasts AC and DC?
A.AC always has zero frequency; DC continuously reverses polarity
B.DC flows in one direction; AC periodically reverses direction
C.AC can exist only inside batteries; DC only on power grids
D.DC voltage is always higher than AC for the same wire size
Explanation: Direct current (DC) maintains a single polarity/direction; alternating current (AC) reverses periodically. Control panels often mix AC mains with DC control supplies.
6In a parallel combination of two unequal resistors connected to a supply, which statement is true?
A.The same current flows through each resistor
B.Each resistor has the same voltage across it
C.Total resistance equals the sum of both resistors
D.Power in each resistor must be identical
Explanation: Parallel branches share the same voltage. Currents split inversely with resistance; total resistance is less than the smallest branch resistance.
7A four-band resistor colour code is used mainly to determine:
A.Only the manufacturer logo and packing date
B.Resistance value and tolerance from band colours
C.Exact inductance in henries
D.Only the maximum soldering temperature
Explanation: Four-band colour coding encodes significant digits, multiplier, and tolerance so technicians can read resistance without a meter, then verify with a multimeter.
8A step-down transformer is primarily used to:
A.Increase frequency of the supply
B.Convert DC to higher-voltage DC by magnetic coupling alone
C.Reduce secondary AC voltage relative to the primary AC voltage
D.Store charge like a large capacitor
Explanation: A transformer couples AC magnetically between windings. A step-down unit has fewer secondary turns, producing a lower secondary voltage for loads and control supplies.
9Which device is a semiconductor that ideally allows current mainly in one direction?
A.Resistor
B.Diode
C.Inductor
D.Incandescent lamp filament
Explanation: A diode conducts strongly in forward bias and blocks (ideally) in reverse bias. Panel and power-supply work frequently uses diodes for rectification and polarity protection.
10An NPN bipolar junction transistor has three terminals commonly named:
A.Anode, cathode, and gate only
B.Collector, base, and emitter
C.Primary, secondary, and core
D.Live, neutral, and earth only
Explanation: BJT terminals are collector, base, and emitter. Identifying NPN vs PNP and terminals is a curriculum practical for component identification.
