1According to Ohm’s law, the current I through a resistive load equals:
A.Voltage times resistance (I = V × R)
B.Voltage divided by resistance (I = V / R)
C.Resistance divided by voltage (I = R / V)
D.Voltage plus resistance (I = V + R)
Explanation: Ohm’s law states I = V / R (or V = I × R) for a conductor at constant temperature. Field technicians use it when estimating current draw of AC loads from nameplate voltage and resistance.
2A room AC heater element of 24 Ω is supplied at 240 V. Approximate current is:
A.5 A
B.10 A
C.0.1 A
D.5760 A
Explanation: I = V / R = 240 / 24 = 10 A. Simple Ohm’s law calculation is common in electrical foundation units of the VOC Field Technician Air Conditioner syllabus.
3Power consumed by a purely resistive load equals:
A.P = V / I only
B.P = V × I (also I²R or V²/R)
C.P = R / I only
D.P = V + I + R
Explanation: Electrical power P = V × I. For a resistor, equivalently P = I²R = V²/R. AC technicians use power to size wiring, breakers, and understand energy use of compressors and heaters.
4A 1.5-ton split AC draws about 8 A at 230 V during steady cooling. Approximate electrical power is:
A.About 1.84 kW
B.About 18.4 W
C.About 230 kW
D.About 0.035 kW
Explanation: P = V × I = 230 × 8 = 1840 W ≈ 1.84 kW. This order of magnitude matches a typical mid-size residential split AC electrical input (not the same as refrigeration tonnage in isolation).
5Three equal 12 Ω resistors are connected in series across a supply. Total resistance is:
A.4 Ω
B.12 Ω
C.36 Ω
D.144 Ω
Explanation: Series resistances add: R_total = R1 + R2 + R3 = 12 + 12 + 12 = 36 Ω. Series addition is a core DC circuit skill in foundation electrical units.
6Two equal 30 Ω resistors are connected in parallel. Equivalent resistance is:
A.60 Ω
B.30 Ω
C.15 Ω
D.900 Ω
Explanation: For two equal resistors in parallel, R_eq = R/2 = 15 Ω. More generally 1/R_eq = 1/R1 + 1/R2. Parallel paths lower total resistance and raise total current for a given voltage.
7The SI unit of electrical energy is the joule (J). One kilowatt-hour (kWh) equals:
A.1 J
B.1000 J
C.3.6 × 10⁶ J
D.360 J
Explanation: 1 kWh = 1000 W × 3600 s = 3,600,000 J = 3.6 × 10⁶ J. Energy meters and electricity bills use kWh; understanding the conversion supports power-and-energy foundation topics.
8In a pure series circuit, which quantity is the same through every component?
A.Voltage drop
B.Current
C.Resistance
D.Power dissipated
Explanation: Series circuits have one current path, so the same current flows through each component. Voltage divides across series resistances; power can differ if resistances differ.
9Which statement correctly contrasts AC and DC for AC field work?
A.AC always has zero frequency; DC continuously reverses polarity
B.DC flows in one direction; AC periodically reverses direction
C.Mains room AC compressors always run only on pure battery DC
D.DC voltage is always higher than AC for the same wire size
Explanation: Direct current (DC) maintains a single polarity/direction; alternating current (AC) reverses periodically. Indian room AC units are typically single-phase AC mains powered, though internal electronics may use DC rails.
10The SI unit of electric current is the:
A.Volt (V)
B.Ohm (Ω)
C.Ampere (A)
D.Watt (W)
Explanation: Current is measured in amperes (A). Voltage is volts, resistance ohms, and power watts. Clamp meters used on AC service measure current in amperes without opening the circuit when used correctly.
