1According to Ohm's Law, which mathematical formula correctly expresses the relationship between voltage (V), current (I), and resistance (R)?
A.V = I × R
B.V = I / R
C.V = I + R
D.V = R / I
Explanation: Ohm's Law states that the voltage across a conductor is directly proportional to the current flowing through it and its resistance. The fundamental formula is V = I × R, from which I = V / R and R = V / I are derived.
2A 100 Ω resistor is connected across a 12 V DC power supply. What is the current flowing through the resistor?
A.0.12 A
B.1.2 A
C.8.33 A
D.1200 A
Explanation: Using Ohm's Law (I = V / R), the current is calculated as I = 12 V / 100 Ω = 0.12 A (or 120 mA). This demonstrates how resistance limits current flow in a DC circuit.
3Two resistors with values of 10 Ω and 20 Ω are connected in series. What is their total equivalent resistance?
A.30 Ω
B.6.67 Ω
C.200 Ω
D.10 Ω
Explanation: In a series circuit, total resistance is the simple sum of individual resistances: R_total = R1 + R2 = 10 Ω + 20 Ω = 30 Ω. The combined resistance is always greater than any individual resistor.
4Two identical 20 Ω resistors are connected in parallel. What is the total equivalent resistance of the combination?
A.10 Ω
B.40 Ω
C.20 Ω
D.400 Ω
Explanation: For two identical resistors connected in parallel, the total resistance is half the value of one resistor: R_total = R / 2 = 20 Ω / 2 = 10 Ω. Using the parallel formula (1/R_total = 1/20 + 1/20 = 2/20), R_total = 20/2 = 10 Ω.
5A electric heating element has a resistance of 50 Ω and carries a current of 2 A. What is the electrical power dissipated by the heater?
A.200 W
B.100 W
C.25 W
D.400 W
Explanation: Electrical power dissipated in a resistor is calculated using P = I² × R. Here, P = (2 A)² × 50 Ω = 4 × 50 = 200 W (Watts).
6What is the SI unit used to measure electric current?
A.Ampere
B.Volt
C.Ohm
D.Watt
Explanation: Electric current is defined as the rate of flow of electric charge (Coulombs per second) and its SI unit is the Ampere (A).
7Which electrical parameter represents the force or pressure that pushes electrons through a conductor?
A.Voltage
B.Resistance
C.Capacitance
D.Inductance
Explanation: Voltage (also called electromotive force or potential difference) is the electrical pressure that drives electrons through a circuit, measured in Volts.
8Which property of a material determines how strongly it opposes the flow of electric current?
A.Resistance
B.Conductance
C.Voltage
D.Frequency
Explanation: Electrical resistance is the intrinsic property of a material or component that opposes the flow of electric current, converting electrical energy into heat.
9What does Kirchhoff's Current Law (KCL) state regarding any node (junction) in an electrical circuit?
A.The total current entering a junction equals the total current leaving it.
B.The sum of all voltages around a closed loop is zero.
C.Current increases proportionally with resistance.
D.Total power in a parallel circuit is zero.
Explanation: Kirchhoff's Current Law (KCL) is based on the conservation of electric charge. It states that the algebraic sum of all currents entering a circuit node must equal the sum of currents leaving that node.
10According to Kirchhoff's Voltage Law (KVL), what is the sum of all electrical potential differences (voltages) around any closed loop in a circuit?
A.Zero
B.Equal to total resistance
C.Equal to total current
D.Infinite
Explanation: Kirchhoff's Voltage Law (KVL) states that the algebraic sum of all potential differences (supply voltages and voltage drops) around any closed circuit loop is equal to zero, reflecting the law of conservation of energy.

Assam ASSEB HSLC NSQF Electronics and Hardware Study Tips from Top Performers

1Memorize Ohm's Law formulas: V = I × R, I = V / R, and R = V / I.
2Remember: High voltage is measured in PARALLEL; Current is measured in SERIES.
3Gold band = 5% tolerance; Silver band = 10% tolerance.
4A dry or cold solder joint looks dull, grainy, and rounded instead of shiny and smooth.
5Always discharge large filter capacitors in power supplies before touching or testing components.

Frequently Asked Questions

What is NSQF Electronics and Hardware Level 2 in Assam ASSEB Class 10?

It is a vocational course under the National Skills Qualifications Framework (NSQF) offered in ASSEB Class 10, preparing students as Field Technician / Electronics Assembly Technician.

What main topic areas are included in the exam?

The exam covers Basic Electricity & Circuit Fundamentals, Passive & Active Electronic Components, Measuring Instruments & Circuit Testing, Soldering & PCB Assembly, and Home Appliance Troubleshooting & ESD Protection.

How do you test a diode using a digital multimeter?

Set the DMM to Diode test mode. Connect red probe to anode and black probe to cathode; a silicon diode should read approx 0.5V to 0.7V forward voltage. Reversing the probes should display OL (Open Loop).

Why is flux used during electronic soldering?

Flux cleans the metal surfaces by removing oxide films when heated, prevents oxidation during soldering, and allows molten solder to flow evenly over pads and leads.

How are these practice questions structured?

All 100 questions follow standard 4-option multiple-choice format with detailed explanations, distractor analysis for wrong options, lastUpdated date (2026-07-30), and practical lab tips.
