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.
