Sample Maharashtra SSC Electronics Technology Pre-Voc/NSQF Practice Questions

Try these sample questions to review concepts for the Maharashtra SSC Electronics Technology Pre-Voc/NSQF exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A semiconductor material has electrical conductivity that is typically:
A.Between that of a good conductor and a good insulator
B.Higher than pure copper in all conditions
C.Exactly zero at all temperatures
D.Identical to air at room temperature
Explanation: Semiconductors such as silicon and germanium conduct better than insulators but far less than metals under normal conditions. Their conductivity rises strongly with temperature and doping, which is why they sit between conductors and insulators in the resistivity hierarchy.
2Silicon atoms in a pure crystal form bonds mainly using how many valence electrons?
A.Four
B.One
C.Eight free metallic electrons per atom
D.Zero valence electrons
Explanation: Silicon is in Group 14 and has four valence electrons. In the crystal lattice each atom shares these with four neighbours to form covalent bonds, leaving almost no free carriers in pure silicon at very low temperature.
3Doping pure silicon with a Group 15 element such as phosphorus produces mainly:
A.An n-type semiconductor with electrons as majority carriers
B.A perfect insulator at room temperature
C.A p-type semiconductor with holes as majority carriers
D.A superconductor below 0 °C only
Explanation: Group 15 donors have five valence electrons. Four bond into the lattice and the fifth becomes a free electron near the conduction band, so electrons are majority carriers in n-type material.
4A p-type semiconductor is formed by adding which kind of impurity to silicon?
A.A Group 13 acceptor such as boron
B.A Group 15 donor such as phosphorus
C.Pure gold foil only
D.Distilled water
Explanation: Group 13 atoms have three valence electrons. When they replace silicon, a hole is created in the bonding structure. Holes act as majority carriers in p-type material.
5In a silicon PN junction diode under forward bias, the external source is connected so that:
A.The P-side is more positive than the N-side
B.The N-side is more positive than the P-side
C.Both sides are left floating with no voltage
D.Only AC is applied with zero average voltage forever
Explanation: Forward bias applies positive voltage to the P-region and negative to the N-region. This reduces the barrier potential so majority carriers can cross the junction and produce large forward current after the knee voltage.
6The approximate knee (cut-in) voltage of a silicon diode at room temperature is about:
A.0.7 V
B.0.05 V
C.12 V
D.100 V
Explanation: Silicon PN diodes typically begin significant forward conduction near 0.6–0.7 V at room temperature. Germanium is lower (~0.3 V), while power or LED devices can differ.
7Under reverse bias (below breakdown), an ideal silicon diode ideally:
A.Conducts only a very small reverse leakage current
B.Acts as a perfect short circuit
C.Produces continuous large AC power by itself
D.Becomes a permanent magnet
Explanation: Reverse bias widens the depletion region. Only minority-carrier leakage flows until the reverse voltage reaches breakdown. Ideal textbook models often treat reverse current as nearly zero.
8A light-emitting diode (LED) emits light primarily when it is:
A.Forward biased with sufficient current
B.Always reverse biased beyond breakdown
C.Left with both leads open in darkness only
D.Shorted with a thick copper bar
Explanation: In a forward-biased LED, injected carriers recombine and release energy as photons. Colour depends on semiconductor band gap. Reverse bias is not used for normal light emission.
9A Zener diode is mainly used in power circuits to:
A.Provide a reference or regulated voltage in reverse breakdown
B.Replace transformers as a primary step-up device
C.Generate radio waves without a power source
D.Store large amounts of electrostatic energy like a supercapacitor
Explanation: Zener diodes are designed to operate safely in reverse breakdown at a specified voltage. With a series resistor they form simple shunt regulators and reference sources.
10In a bipolar junction transistor (BJT), the three terminals are called:
A.Emitter, base, and collector
B.Anode, cathode, and gate only
C.Source, drain, and body only
D.Primary, secondary, and core
Explanation: A BJT has emitter, base, and collector regions. Small base current controls larger collector–emitter current in the active region, enabling amplification and switching.

About the Maharashtra SSC Electronics Technology Pre-Voc/NSQF Exam

Maharashtra SSC Electronics Technology under MSBSHSE is a Class 10 pre-vocational / NSQF skill subject (commonly subject code 93 on modern SSC subject lists; confirm your hall ticket). Core learning themes include semiconductor basics, digital orientation, circuits, instruments, PCB assembly, troubleshooting, and safety. Official assessment often combines theory with practical, project, performance, or school-based evidence depending on the subject scheme. About 35% is widely reported as the SSC subject pass floor—confirm the year's notification. This free bank provides English four-option MCQs for knowledge and judgment practice only—pair with official school materials via mahahsscboard.in.

Exam sponsor: Maharashtra State Board of Secondary and Higher Secondary Education (MSBSHSE), Pune. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

Typical SSC pre-vocational / NSQF skill subject pattern: written theory and/or practical/project/performance/internal evidence as per scheme (confirm year's school/board notice). Local bank: English MCQ study adaptation only.

Time Limit

As notified on the year's MSBSHSE SSC timetable for theory where applicable; other components scheduled separately

Frequently Asked Questions

How is Maharashtra SSC Electronics Technology officially examined?

It is examined under the Maharashtra Secondary School Certificate as a Class 10 pre-vocational / NSQF skill subject (commonly code 93). Logistics may combine written theory with practical, project, performance, or internal assessment depending on the subject scheme. Candidates generally need about 35% with separate floors as notified. Confirm the year's syllabus and circulars with your school and mahahsscboard.in.

Is this practice bank the same format as the official SSC paper?

No. Official assessment may mix written theory with practical, project, or performance evidence. This bank is an English-language multiple-choice study adaptation for concepts and judgment only—not an official blueprint replica or practical/performance certification substitute.

What subject code is used for Electronics Technology?

Modern Maharashtra SSC subject lists commonly show code 93 for Electronics Technology. Always confirm the code printed on your hall ticket and school registration because board circulars can refine titles or codes.

In which languages is the official assessment offered?

Maharashtra SSC subject materials and papers are commonly available in English and Marathi mediums (and other media as notified for some subjects). This practice bank is an English-language study adaptation, not an official translation of the board paper.

How should I use these free MCQs?

Study your school syllabus first, then drill this bank by category. Read every wrong-option explanation, keep a practical/project journal if required, and re-test weak topics under timed conditions before board week.
