Sample Maharashtra HSC Electronics (Bifocal) Practice Questions

Try these sample questions to review concepts for the Maharashtra HSC Electronics (Bifocal) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A 12 V battery is connected across a 4 Ω resistor. What is the current in the circuit?
A.48 A
B.3 A
C.0.33 A
D.16 A
Explanation: By Ohm’s law, I = V/R = 12 V / 4 Ω = 3 A. Current equals voltage divided by resistance for a simple resistive circuit.
2Two resistors of 6 Ω and 3 Ω are connected in series across a 18 V supply. What is the total circuit current?
A.3 A
B.2 A
C.6 A
D.9 A
Explanation: Series resistance R_total = 6 + 3 = 9 Ω. I = V/R_total = 18/9 = 2 A. In series, the same current flows through every resistor.
3Two resistors of 12 Ω and 6 Ω are connected in parallel. What is the equivalent resistance?
A.18 Ω
B.9 Ω
C.2 Ω
D.4 Ω
Explanation: For two parallel resistors, 1/R_eq = 1/12 + 1/6 = 1/12 + 2/12 = 3/12, so R_eq = 4 Ω. Parallel equivalent is always less than the smaller branch resistance.
4A 10 Ω resistor carries 2 A. What power is dissipated in the resistor?
A.40 W
B.20 W
C.5 W
D.12 W
Explanation: Power P = I²R = (2)² × 10 = 4 × 10 = 40 W. Equivalently P = VI with V = IR = 20 V gives P = 20 × 2 = 40 W.
5Three 6 Ω resistors are connected in parallel. What is the equivalent resistance?
A.18 Ω
B.6 Ω
C.2 Ω
D.3 Ω
Explanation: Equal resistors in parallel: R_eq = R/n = 6/3 = 2 Ω. Alternatively 1/R_eq = 3×(1/6) = 1/2.
6A series circuit has R1 = 4 Ω and R2 = 8 Ω across 24 V. What voltage appears across R2?
A.8 V
B.12 V
C.16 V
D.24 V
Explanation: Voltage divider: V2 = V × (R2/(R1+R2)) = 24 × (8/12) = 16 V. Current I = 24/12 = 2 A, so V2 = IR2 = 16 V.
7How much energy (in joules) does a 100 W lamp use in 5 minutes?
A.30 000 J
B.500 J
C.20 J
D.100 J
Explanation: Energy E = P × t. Convert 5 minutes to 300 s. E = 100 W × 300 s = 30 000 J.
8Four resistors of 8 Ω each are connected as two series pairs placed in parallel with each other. What is R_eq?
A.4 Ω
B.16 Ω
C.8 Ω
D.32 Ω
Explanation: Each series pair is 8+8 = 16 Ω. Two 16 Ω branches in parallel give R_eq = 8 Ω. Series-then-parallel reduction is the standard approach.
9A wire has resistance 10 Ω. If both its length and cross-sectional area are doubled, the new resistance is approximately:
A.10 Ω
B.5 Ω
C.20 Ω
D.40 Ω
Explanation: R = ρL/A. Doubling L multiplies R by 2; doubling A divides R by 2. Net factor is 1, so resistance stays 10 Ω.
10In a pure resistive AC circuit, the average power is maximum when the phase angle between voltage and current is:
A.90°
B.45°
C.180°
D.0°
Explanation: Average power P = VI cos φ. For a pure resistor, φ = 0°, cos 0° = 1, so power factor is unity and average power is maximum for given V and I rms.

Assessment

Maharashtra Higher Secondary Bifocal Electronics is an HSC (Class 12) technical elective under MSBSHSE, Pune (subject code C2). Official logistics commonly describe two theory papers — Paper I Applied Electronics and Paper II Digital Electronics — each about 50 marks over about 3 hours, with substantial practical assessment (experiments, oral, journal, project) historically bringing total marks toward about 200 (about 100 theory + 100 practical). Qualifying typically requires about 35% with separate theory/practical floors as notified. Paper I covers instruments (CRT/CRO, function generator, DMM), DC power supplies, transducers, operational amplifiers, modern electronic communication, and integrated circuits. Paper II covers number systems, logic gates, logic families, combinational logic, flip-flops/registers/counters, A/D–D/A converters, and computer fundamentals. Foundation Class 11 themes (basic electricity, passive components, semiconductors, workshop practice) support the two-year course. Distinct from vocational Electronics Technology (EA/EB/EC) and NSQF field-technician pathways. English/Marathi medium materials are typical; this practice bank is an English-language MCQ study adaptation. Confirm current syllabus and circulars on mahahsscboard.in and dvet.gov.in.

Maharashtra HSC Electronics (Bifocal): Suggested Study Strategy

1Practise Ohm’s law, series–parallel R, power P=VI, and rectifier average/PIV ideas weekly — boards reward numerical fluency (~30% numerical weightage as commonly reported).
2Build a one-page op-amp cheat sheet: inverting/non-inverting gain, virtual ground, adder, integrator, comparator.
3Drill binary/hex conversions and truth tables until they are automatic before attempting mux and flip-flop questions.
4Treat practical journal experiments (CRO measurements, power-supply builds, logic-gate kits) as part of the majority practical score.
5After MCQ concept checks, write short answers on CRO block diagram, bridge rectifier with filter, and De Morgan proofs under timed conditions.

Frequently Asked Questions

How is Maharashtra HSC Bifocal Electronics officially examined?

Electronics is examined under the Maharashtra Higher Secondary Certificate Examination as a Class 12 bifocal technical elective (MSBSHSE subject code C2). Logistics commonly describe two theory papers — Paper I Applied Electronics and Paper II Digital Electronics — each about 50 marks over about 3 hours, plus practical assessment (experiments, oral, journal, project) that historically brings the subject toward about 200 marks total. Candidates generally need about 35% with separate theory/practical floors as notified. Confirm the year’s syllabus, timetable, and circulars on mahahsscboard.in and DVET Maharashtra notices.

Is this practice bank the same format as the official HSC Electronics paper?

No. Official MSBSHSE bifocal Electronics assessment mixes written theory (including numerical problems) with heavy practical skills (experiments, journal, project, viva). This bank is an English-language multiple-choice study adaptation for concepts, safety, and calculations only — not an official translation, blueprint replica, or full practical/written-paper simulation.

What syllabus does this bank follow?

It is aligned to Maharashtra HSC / Class 12 Bifocal Electronics (subject code C2): Paper I Applied Electronics (instruments, DC power supplies, transducers, op-amps, modern communication, ICs) and Paper II Digital Electronics (number systems, logic gates, logic families, combinational logic, flip-flops, A/D–D/A, computer fundamentals), plus Class 11 foundation themes (basic electricity, R/C/L, semiconductors, workshop practice). It is intentionally distinct from vocational Electronics Technology (EA/EB/EC) and NSQF field-technician scope. Always confirm the current MSBSHSE/DVET circular for your year.

What is the pass mark for Maharashtra HSC Bifocal Electronics?

MSBSHSE commonly requires a minimum of about 35% in each subject, often with separate floors for theory and practical under bifocal patterns. Always verify the current Higher Secondary notification for your sitting.

What is the official subject code for HSC Bifocal Electronics?

MSBSHSE bifocal subject lists use code C2 for Electronics. Confirm against your college subject registration and admit card. Do not confuse C2 with vocational Electronics Technology codes (EA/EB/EC).

Where should I check official syllabus, papers, and results?

Use the MSBSHSE site at mahahsscboard.in for circulars and question papers, mahahsscboard.org/hscsub.htm for subject-code orientation, DVET Maharashtra (dvet.gov.in) for technical bifocal syllabus materials, and your divisional board portals for results and hall tickets.
