1A resistive test load has a resistance of 4 ohms and is connected across a 12-volt battery supply. According to Ohm's law (I = V / R), what current flows through the load?

A.0.33 amperes

B.3.0 amperes

C.8.0 amperes

D.48.0 amperes

Explanation: According to Ohm's law, current equals voltage divided by resistance: I = V / R = 12 V / 4 ohms = 3.0 A. This calculation treats the load as a resistor with a constant resistance.

2A vehicle headlight bulb draws 5 amperes of current when operated on a nominal 12-volt circuit. What is the electrical power rating of the bulb?

A.2.4 watts

B.17 watts

C.60 watts

D.72 watts

Explanation: Electrical power is calculated using P = V * I. At the stated operating point, 12 volts multiplied by 5 amperes gives 60 watts. Actual bulb ratings depend on the specified lamp and test voltage.

3In automotive electrical theory, what physical quantity represents the electromotive force (EMF) that causes free electrons to flow through an automotive circuit?

A.Current, measured in amperes

B.Resistance, measured in ohms

C.Voltage, measured in volts

D.Frequency, measured in hertz

Explanation: Voltage, or electromotive force, is the electrical potential difference between two points that forces free electrons to drift through a conductor. Current is the rate of flow of those electrons, and resistance opposes that flow.

4What type of electrical current is delivered by an automotive lead-acid storage battery to power vehicle accessories?

A.Direct current (DC), flowing continuously in one direction

B.Alternating current (AC), reversing direction at 50 Hz

C.Unidirectional current that falls to zero between every alternator half-cycle

D.Three-phase alternating current before rectification

Explanation: A discharging battery supplies direct current: the current does not reverse polarity as AC does. Its magnitude can change as loads switch, so DC does not mean an unchanging current value.

5Two 3-ohm resistors are connected in series across a 12-volt vehicle power source. What is the total circuit resistance and the resulting current flowing through the circuit?

A.Total resistance = 1.5 ohms; current = 8.0 amperes

B.Total resistance = 6.0 ohms; current = 2.0 amperes

C.Total resistance = 6.0 ohms; current = 0.5 amperes

D.Total resistance = 9.0 ohms; current = 1.33 amperes

Explanation: In a series circuit, resistances add directly: R_total = R1 + R2 = 3 ohms + 3 ohms = 6.0 ohms. The current flowing through the circuit is then I = V / R_total = 12 V / 6.0 ohms = 2.0 A.

6Two 4-ohm auxiliary lamps are wired in parallel across a 12-volt battery supply. What is the equivalent resistance of the parallel combination and the total current supplied by the battery?

A.Equivalent resistance = 2.0 ohms; total current = 6.0 amperes

B.Equivalent resistance = 8.0 ohms; total current = 1.5 amperes

C.Equivalent resistance = 2.0 ohms; total current = 3.0 amperes

D.Equivalent resistance = 1.0 ohm; total current = 12.0 amperes

Explanation: For two identical resistors in parallel, the equivalent resistance is R / 2 = 4 / 2 = 2.0 ohms. The total current drawn from the 12 V source is I = V / R_eq = 12 V / 2.0 ohms = 6.0 A (or 3.0 A through each lamp branch).

7According to Kirchhoff's Current Law (KCL), if a main harness wire feeds 14 amperes into a splice node that splits into three branch circuits carrying 5 amperes, 6 amperes, and unknown current I_3, what is I_3?

A.1.0 ampere

B.3.0 amperes

C.11.0 amperes

D.25.0 amperes

Explanation: Kirchhoff's Current Law states that the algebraic sum of currents entering a junction equals the sum of currents leaving: I_total = I_1 + I_2 + I_3. Therefore, 14 A = 5 A + 6 A + I_3, which yields I_3 = 14 - 11 = 3.0 A.

8In an automotive series circuit with three components connected across a 12-volt battery, the voltage drop across the first load is 3.5 volts and across the second load is 4.5 volts. What is the voltage drop across the third load?

A.4.0 volts

B.8.0 volts

C.12.0 volts

D.20.0 volts

Explanation: By Kirchhoff's Voltage Law, the sum of voltage drops in a closed series loop equals the source voltage: V_source = V_1 + V_2 + V_3. Therefore, 12.0 V = 3.5 V + 4.5 V + V_3, meaning V_3 = 12.0 V - 8.0 V = 4.0 V.

9Which of the following physical changes will double the electrical resistance of an automotive copper wiring conductor?

A.Doubling its cross-sectional area while keeping length constant

B.Doubling its length while keeping cross-sectional area constant

C.Halving its length while keeping cross-sectional area constant

D.Decreasing its operating temperature by 50 degrees Celsius

Explanation: Resistance is directly proportional to conductor length and inversely proportional to cross-sectional area (R = rho * L / A). Doubling the length (L) doubles the resistance (R).

10A corroded ground terminal in a radiator fan circuit develops an unwanted resistance of 0.5 ohms. If the fan draws 10 amperes of current, how much heat power is wasted at the corroded terminal?

A.5 watts

B.20 watts

C.50 watts

D.100 watts

Explanation: Power dissipated in resistance is given by P = I^2 * R. With I = 10 A and R = 0.5 ohms, P = (10)^2 * 0.5 = 100 * 0.5 = 50 watts. This significant heat dissipation can melt terminal insulation or cause an electrical fire.

VETA Auto Electric CBA: Suggested Study Strategy

1Work circuit calculations from the stated values and units; distinguish electrical input power from mechanical motor output.

2Practise reading the actual wiring diagram, making loaded voltage-drop measurements and checking the manufacturer's test limits before selecting parts.

3Combine these questions with supervised workshop work, practical fault finding, written explanations and the assignments required by your centre.

Frequently Asked Questions

Is the Auto Electric assessment current in 2026?

Yes. VETA's June 2026 Competence Based Assessment (CBA) results list Auto Electric at Levels 1, 2 and 3.

What languages does VETA use for this assessment?

VETA's 2023 results index lists Auto Electric in English and Kiswahili curriculum streams. Current 2026 delivery and response-language permissions were not verified; confirm them for your centre, level and sitting. This bank is an English-language MCQ study adaptation, not an official translation or a simulation of the exam's language environment.

Does this bank replace practical assessment or coursework?

No. VETA CBA uses continuous and final assessment. Auto Electric results include practical, theory, field attachment and supporting subjects. The Form I-IV vocational syllabus also describes oral questions, practical assignments, presentations and projects. Complete the requirements of your own route; MCQs practise knowledge and decisions without demonstrating performance.

Are these official topic weights or a complete syllabus simulation?

No. The bank uses independently selected auto-electrical study topics. The VETA-published syllabus on the TIE site supplies authoritative occupational scope, but it covers the broader Form I-IV vocational programme and is not a published CBA paper blueprint. No official percentage topic distribution is claimed.

Who is eligible?

VETA's general long-course guidance describes entry after primary education or higher, selection and centre-specific joining instructions, with progression based on the preceding CBA level. Ask the registered centre which Auto Electric route and entry requirements apply. Do not assume informal experience alone grants entry to this assessment.
