Sample Odisha CHSE +2 Vocational Audio Video Technique Practice Questions

Try these sample questions to review concepts for the Odisha CHSE +2 Vocational Audio Video Technique exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In Audio Video Technique workshop practice, a good electrical conductor is a material that:
A.Allows electric charge to flow easily because it has many free electrons
B.Always blocks current completely under all voltages
C.Is defined only by mechanical hardness, not free electrons
D.Must be a semiconductor doped with rare-earth metals
Explanation: Conductors (copper, aluminium, silver, etc.) have many free electrons that move under an applied electric field, so current flows easily. That property is exactly why they are used for wiring and chassis connections in AV equipment.
2Which pair correctly matches a common workshop material with its typical electrical role?
A.Mica — preferred mains-live stranded flexible cord
B.Copper wire — conductor; porcelain or PVC — insulator
C.Glass — best high-current bus bar conductor
D.Rubber — preferred chassis ground strap material
Explanation: Copper is a standard conductor for interconnects. Porcelain, PVC, rubber, mica, and glass are insulating materials used to separate live parts. Matching material class to role is a core Unit-I materials skill.
3A fuse is intended primarily to:
A.Filter RF noise from the antenna cable
B.Act as a permanent short across the supply
C.Open the circuit when current exceeds its rated fusing value, protecting wiring and equipment
D.Increase voltage to the load during brownouts
Explanation: A fuse melts (opens) when current exceeds its rating (fusing current/time characteristic). That interrupts the circuit and protects conductors and devices from overcurrent damage—standard first-year materials safety content.
4Flux is used during soldering mainly to:
A.Raise the melting point of solder above the copper’s melting point
B.Provide structural strength instead of solder metal
C.Insulate the finished joint with a thick ceramic layer
D.Clean oxides from metal surfaces so solder can wet the joint properly
Explanation: Flux chemically removes and prevents reformation of oxides so molten solder can wet copper pads and component leads, forming a reliable low-resistance joint—core soldering practice in Paper-I practicals.
5A single-pole single-throw (SPST) switch is best described as a switch that:
A.Opens or closes one circuit path with one moving contact arrangement
B.Always reverses the polarity of a DC motor automatically
C.Must have four poles for stereo audio
D.Can only be operated by a remote infrared receiver
Explanation: SPST means one pole (one circuit) and single throw (on/off between two terminals). It is the simplest on/off switch type listed under types of switches in common materials units.
6According to Ohm’s law, if resistance is held constant and voltage across a resistor doubles, the current:
A.Becomes zero
B.Doubles
C.Halves
D.Remains exactly the same
Explanation: Ohm’s law is V = IR (or I = V/R). With R fixed, current is proportional to voltage, so doubling V doubles I. Verification of Ohm’s law is an explicit first-year practical.
7A carbon film resistor band code reads brown-black-red-gold. Its nominal resistance is approximately:
A.100 Ω with ±1% tolerance
B.1 MΩ with ±10% tolerance
C.1 000 Ω (1 kΩ) with ±5% tolerance
D.10 Ω with ±20% tolerance
Explanation: Standard 4-band code: brown=1, black=0, red=×100 → 10×100 = 1000 Ω. Gold = ±5% tolerance. Colour coding is a Unit-II basic-components requirement.
8Two 4 Ω resistors connected in series have an equivalent resistance of:
A.2 Ω
B.4 Ω
C.16 Ω
D.8 Ω
Explanation: Series resistances add: Req = R1 + R2 = 4 + 4 = 8 Ω. Series/parallel combinations are core Unit-II content.
9Kirchhoff’s current law (KCL) states that at a circuit node:
A.The algebraic sum of currents entering and leaving the node is zero
B.The product of all branch currents equals one
C.Voltage is identical in every branch regardless of resistance
D.Power is conserved only if all devices are capacitors
Explanation: KCL expresses charge conservation: ΣI_in = ΣI_out (algebraic sum zero). Kirchhoff’s laws appear explicitly in the AVT first-year component unit and practicals.
10Kirchhoff’s voltage law (KVL) around a closed loop means:
A.Only AC sources can appear in a valid loop
B.The algebraic sum of voltage rises and drops around the loop is zero
C.Current is the same in every element even in parallel branches
D.Resistance must be zero for any closed path
Explanation: KVL is energy conservation around a loop: sum of potential differences is zero. It is verified alongside Ohm’s law in first-year practical work.

Odisha CHSE +2 Vocational Audio Video Technique: Suggested Study Strategy

1Alternate MCQ drills with short written definitions and block diagrams—official theory is not pure MCQ.
2Practise real lab skills weekly: resistor colour reading, multimeter V/I/R checks, soldering/desoldering, and diode/transistor junction tests.
3Memorise Ohm’s law forms and series/parallel rules; work numeric examples for resistors and simple power (P=VI, I²R).
4Draw the linear power-supply chain (transformer → rectifier → filter → regulator) and an SMPS efficiency idea before memorising only words.
5For radio, contrast AM vs FM and sketch superhet RF → mixer/LO → IF → detector → AF.
6For TV, link symptoms to stages: dead set → power first; sound OK/no picture → video/display path.
7Treat practical records and viva as mark-bearing: explain procedures, safety, and instrument connections aloud.
8Use official Part-1-1 unit lists as your checklist; this bank accelerates theory recall but does not replace CHSE practicals.
