Module 1: Basic Electricity & Electronics (Questions 1–30)
,1. What is the fundamental formula for Ohm's Law?
A) $P = V \times I$
B) $V = I \times R$
C) $R = V \times I$
D) $I = V \times R$
Answer: B
Rationale: Ohm's Law states that Voltage ($V$) equals Current ($I$) multiplied by
Resistance ($R$).
2. In a series circuit, what happens to the total resistance as more resistors are
added?
A) It decreases
B) It remains unchanged
C) It increases
D) It drops to zero
Answer: C
Rationale: In series circuits, total resistance is the sum of all individual resistances
($R_{total} = R_1 + R_2 + R_3...$).
3. In a parallel circuit, what remains constant across all parallel branches?
,A) Current
B) Resistance
C) Power
D) Voltage
Answer: D
Rationale: Voltage is identical across all parallel branches in a circuit.
4. Calculate the current in a 12V DC circuit with a total resistance of 24 Ohms.
A) 0.5 Amps
B) 2.0 Amps
C) 288 Amps
D) 12 Amps
Answer: A
Rationale: $I = \frac{V}{R} = \frac{12}{24} = 0.5\text{ Amps}$.
5. What type of power is typically supplied by backup batteries in alarm control
panels?
A) Alternating Current (AC)
B) Direct Current (DC)
, C) Pulsing AC
D) High-frequency AC
Answer: B
Rationale: Sealed lead-acid (SLA) backup batteries provide Direct Current (DC).
6. What component is used to convert 120VAC household current to a lower AC
voltage suitable for alarm transformers?
A) Rectifier
B) Step-down Transformer
C) Capacitor
D) Inverter
Answer: B
Rationale: Step-down transformers lower 120VAC line voltage to low-voltage AC (typically
16.5VAC or 24VAC).
7. Which electronic component converts AC power into DC power?
A) Rectifier
B) Transformer
C) Resistor
D) Inductor
