1According to Ohm Law, what is the voltage across a 10-ohm resistor when a current of 2 amperes flows through it?
A.20 V
B.5 V
C.12 V
D.0.2 V
Explanation: Voltage across a resistor is calculated using V = I * R. Multiplying 2 A by 10 ohms gives 20 V. This fundamental relationship governs direct current circuit analysis.
2What is the equivalent resistance of two 100-ohm resistors connected in parallel?
A.200 ohms
B.50 ohms
C.100 ohms
D.25 ohms
Explanation: For identical resistors connected in parallel, the total resistance is equal to the resistance of one resistor divided by the number of resistors. Dividing 100 ohms by 2 yields 50 ohms.
3What fundamental conservation principle forms the basis of Kirchhoff Current Law (KCL)?
A.Conservation of energy
B.Conservation of momentum
C.Conservation of electric charge
D.Conservation of magnetic flux
Explanation: Kirchhoff Current Law states that the algebraic sum of currents entering any electrical node must equal the sum of currents leaving that node. This principle directly expresses the conservation of electric charge, as charge cannot accumulate at an ideal node.
4A sinusoidal AC signal has a peak voltage of 14.14 V. What is its Root Mean Square (RMS) voltage?
A.28.28 V
B.14.14 V
C.7.07 V
D.10.0 V
Explanation: RMS voltage for a pure sine wave is calculated by dividing the peak voltage by the square root of 2 (approximately 1.414). Dividing 14.14 V by 1.414 yields 10.0 V RMS.
5What is the primary function of a decoupling capacitor placed near integrated circuit (IC) power supply pins?
A.Filtering high-frequency noise and stabilizing voltage spikes
B.Increasing overall circuit resistance
C.Converting AC signals into DC voltage
D.Amplifying digital clock signals
Explanation: Decoupling capacitors act as local energy reservoirs right at the IC supply pins. They bypass high-frequency switching noise to ground and maintain stable power rails during sudden current draws.
6A series voltage divider consists of R1 = 1 k-ohm and R2 = 2 k-ohm connected across a 9 V DC source. What is the voltage drop across R2?
A.3 V
B.6 V
C.4.5 V
D.9 V
Explanation: Using the voltage divider formula V_out = V_in * (R2 / (R1 + R2)), we get 9 V * (2000 / 3000) = 6 V. The larger resistor drops two-thirds of the total supply potential.
7What is the time constant (tau) of a series RC circuit containing a 10 k-ohm resistor and a 47 uF capacitor?
A.4.7 seconds
B.0.047 seconds
C.0.47 seconds
D.47 seconds
Explanation: The RC time constant is calculated by multiplying resistance in ohms by capacitance in farads: 10,000 ohms * 0.000047 farads = 0.47 seconds. This represents the time needed to charge the capacitor to roughly 63.2% of full voltage.
8Which semiconductor device allows electric current to flow in only one direction under normal operating conditions?
A.Bipolar transistor
B.Ceramic capacitor
C.Wirewound resistor
D.PN junction diode
Explanation: A PN junction diode conducts current when forward-biased beyond its threshold voltage and blocks current when reverse-biased. This asymmetrical conductivity makes it essential for rectification and reverse-voltage protection.
9When used as a digital electronic switch, in which two operating regions does an NPN Bipolar Junction Transistor (BJT) operate?
A.Cutoff and saturation
B.Active and saturation
C.Cutoff and active
D.Breakdown and pinch-off
Explanation: In digital switching applications, a BJT is driven between cutoff (fully OFF, zero collector current) and saturation (fully ON, minimum collector-emitter voltage). Operating in these extreme states minimizes power dissipation across the transistor.
10An ideal non-inverting operational amplifier circuit has a feedback resistor Rf = 90 k-ohm and an input resistor Rin = 10 k-ohm. What is the closed-loop voltage gain (Av)?
A.9
B.10
C.1
D.90
Explanation: The voltage gain of a non-inverting op-amp configuration is Av = 1 + (Rf / Rin). Substituting 90 k-ohm and 10 k-ohm yields 1 + 9 = 10.
