1Ohm's law states that the voltage across a resistor is equal to:

A.Current multiplied by resistance (V = I × R)

B.Current divided by resistance (V = I / R)

C.Resistance divided by current (V = R / I)

D.Current plus resistance (V = I + R)

Explanation: Ohm's law relates voltage, current, and resistance as V = I × R for an ohmic conductor at constant temperature. From this, I = V / R and R = V / I follow by rearrangement.

2A 12 V supply is connected across a 6 Ω resistor. What is the current through the resistor?

A.0.5 A

B.2 A

C.18 A

D.72 A

Explanation: Using I = V / R: I = 12 V / 6 Ω = 2 A. Always divide voltage by resistance to find current in a simple series DC path.

3The SI unit of electrical resistance is the:

A.Volt

B.Ampere

C.Ohm

D.Watt

Explanation: Resistance is measured in ohms (Ω). Volt measures potential difference, ampere measures current, and watt measures power.

4A resistor primarily:

A.Opposes the flow of electric current

B.Stores energy only as a magnetic field

C.Allows current in only one direction always

D.Amplifies signal power by itself without bias

Explanation: A resistor limits or opposes current according to its resistance value. Energy storage in magnetic fields is inductive behaviour; one-way conduction is diode behaviour; amplification needs active devices with proper bias.

5A capacitor primarily stores energy in the form of:

A.An electric field between its plates

B.A magnetic field around a coil only

C.Chemical energy like a primary battery always

D.Mechanical spring tension

Explanation: A capacitor stores charge and energy in the electric field between conductors (plates) separated by a dielectric. Inductors store energy in magnetic fields; batteries use chemical energy.

6A semiconductor diode ideally allows significant current when it is:

A.Forward biased

B.Reverse biased beyond breakdown only (always the only useful mode)

C.Completely open-circuited with no connection

D.Used only as a fuse wire

Explanation: In normal rectifier/signal use, a diode conducts when forward biased (anode more positive than cathode for silicon by roughly the forward drop). Reverse bias normally blocks current until breakdown (as in Zener operation, which is a special case).

7An LED is a diode that:

A.Emits light when forward biased with proper current

B.Stores large magnetic energy like a transformer

C.Works only on reverse bias for normal illumination

D.Is used only as a mechanical switch

Explanation: A light-emitting diode (LED) produces light when forward biased and current is limited to a safe value (often with a series resistor). Reverse bias is not the normal lighting mode.

8A bipolar junction transistor (BJT) is commonly used as:

A.An amplifier or electronic switch

B.Only a mechanical relay armature

C.Only a pure resistor with fixed colour code

D.Only a chemical battery cell

Explanation: BJTs are active semiconductor devices used for amplification and switching when properly biased. They are not mechanical relays, fixed passive resistors, or chemical cells.

9In a series circuit with two resistors, the same quantity through both resistors is:

A.Current

B.Voltage drop always equal regardless of resistance values

C.Power always equal always

D.Capacitance

Explanation: Series connection means one path: the same current flows through each resistor. Voltage drops divide according to each resistance (V = IR). Power is not automatically equal unless resistances match.

10In a parallel circuit with two resistors across the same supply, the quantity that is the same across both is:

A.Voltage

B.Current through each branch always equal always

C.Resistance of each branch always equal always

D.Magnetic flux only

Explanation: Parallel branches share the same voltage across them. Currents divide inversely with branch resistance. Branch resistances need not be equal.

Karnataka KSEAB SSLC NSQF Electronics and Hardware: Suggested Study Strategy

1Alternate MCQ drills with short written answers because official theory is mixed-format, not pure MCQ.

2Practise real lab skills: resistor colour reading, multimeter voltage/resistance checks, and safe soldering on scrap boards.

3Memorise Ohm’s law forms (V=IR, I=V/R, R=V/I) and work a few numeric examples every revision session.

4Draw series vs parallel sketches and label how current and voltage behave before memorizing formulas.

5Treat workplace safety and employability as mark-bearing content: earthing, PPE, e-waste, and communication appear across NSQF subjects.

6Build practical skill evidence throughout the year; do not leave soldering and viva prep until after theory only.

7Use official KSEAB model papers (22EK) for paper-pattern familiarity; use this bank for rapid theory knowledge checks.
