INDUSTRY | 40 VERIFIED Q&A | DETAILED
RATIONALES | PASS GUARANTEED – A+ GRADED
Q1: Electrical Theory – Series Circuits
In a series circuit, how does current behave?
A. Current is the same at all points in the circuit
B. Current divides among the components
C. Current is zero
D. Current increases at each component
Correct Answer: A
Rationale: In a series circuit, there is only one path for current flow, so the current is the same
through all components. Voltage divides across the components. [100% CORRECT]
Q2: Electrical Theory – Parallel Circuits
In a parallel circuit, how does voltage behave?
A. Voltage is the same across all branches
B. Voltage divides among the branches
C. Voltage is zero
D. Voltage decreases at each branch
Correct Answer: A
Rationale: In a parallel circuit, each branch is connected directly across the power source, so voltage
is the same across all branches. Current divides among the branches. [100% CORRECT]
Q3: Electrical Theory – Kirchhoff's Current Law
What does Kirchhoff's Current Law state?
A. The sum of currents entering a junction equals the sum of currents leaving
B. Voltage around a loop equals zero
C. Current is inversely proportional to resistance
D. Power equals voltage times current
Correct Answer: A
Rationale: Kirchhoff's Current Law (KCL) states that the algebraic sum of currents entering and
leaving a junction is zero. This is based on conservation of charge. [100% CORRECT]
Q4: Electrical Theory – Kirchhoff's Voltage Law
, 2
What does Kirchhoff's Voltage Law state?
A. The sum of voltage drops around a closed loop equals the source voltage
B. Current is the same at all points
C. Resistance is constant
D. Power is conserved
Correct Answer: A
Rationale: Kirchhoff's Voltage Law (KVL) states that the algebraic sum of all voltages around a closed
loop is zero. The sum of voltage drops equals the applied voltage. [100% CORRECT]
Q5: Electrical Components – Transformers
What is the primary function of a transformer?
A. To change AC voltage levels
B. To convert AC to DC
C. To store electrical energy
D. To measure current
Correct Answer: A
Rationale: Transformers step up or step down AC voltage through electromagnetic induction
between primary and secondary coils. They do not work on DC. [100% CORRECT]
Q6: Electrical Components – Diodes
What is the function of a diode?
A. To allow current to flow in only one direction
B. To amplify signals
C. To store charge
D. To measure resistance
Correct Answer: A
Rationale: A diode is a semiconductor device that allows current to flow in one direction (forward
bias) and blocks it in the opposite direction (reverse bias). Used in rectifiers. [100% CORRECT]
Q7: Electrical Components – Capacitors
What is the function of a capacitor in an elevator control circuit?
A. To store electrical energy and smooth voltage fluctuations
B. To increase current
C. To measure temperature
D. To generate power
Correct Answer: A
