Sample BTEB Electrician (EIM) Exam Practice Questions

Try these sample questions to test your BTEB Electrician (EIM) Exam exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A rectangular switch board panel measures 40 cm in length and 25 cm in width. What is its area?
A.650 cm²
B.1000 cm²
C.130 cm²
D.65 cm²
Explanation: Area of a rectangle is found by multiplying length by width: 40 cm × 25 cm = 1000 cm². Trainees must apply this basic formula when estimating material such as sheet metal or board area for fittings.
2If the radius of a circular conduit pipe is 7 cm, what is its diameter?
A.7 cm
B.14 cm
C.21 cm
D.49 cm
Explanation: The diameter of a circle is always twice its radius, so a 7 cm radius gives a 14 cm diameter. This relationship (d = 2r) is used constantly when selecting conduit, cable, and fitting sizes.
3Using π ≈ 22/7, what is the approximate area of a circular junction box cover with a radius of 7 cm?
A.44 cm²
B.154 cm²
C.22 cm²
D.308 cm²
Explanation: The area of a circle is πr². Using π ≈ 22/7 and r = 7 cm gives (22/7) × 7 × 7 = 154 cm². Confusing the area formula with the circumference formula (2πr) is a common workplace calculation error.
4A triangular cable tray support bracket has a base of 12 cm and a height of 8 cm. What is its area?
A.96 cm²
B.48 cm²
C.20 cm²
D.60 cm²
Explanation: The area of a triangle is half the base multiplied by the height: ½ × 12 × 8 = 48 cm². Forgetting to halve the product is a frequent mistake that instead gives the area of a rectangle with the same base and height.
5A rectangular junction box measures 10 cm long, 8 cm wide, and 5 cm deep. What is its internal volume?
A.400 cm³
B.23 cm³
C.80 cm³
D.130 cm³
Explanation: Volume of a rectangular box is length × width × depth: 10 × 8 × 5 = 400 cm³. Trainees calculate volume like this to confirm a box is large enough to safely hold the required connections.
6How many centimeters are there in 2.5 meters of PVC conduit?
A.25 cm
B.250 cm
C.2500 cm
D.0.25 cm
Explanation: Since 1 meter equals 100 centimeters, 2.5 meters equals 2.5 × 100 = 250 centimeters. Converting between meters and centimeters is a routine task when reading drawings marked in different units.
7A cable gland is specified as 1 inch in diameter. Using 1 inch ≈ 2.54 cm, what is this measurement in centimeters (to two decimal places)?
A.1.54 cm
B.2.54 cm
C.25.4 cm
D.0.39 cm
Explanation: One inch converts directly to 2.54 centimeters using the standard conversion factor. Electricians must convert between imperial and metric units because imported fittings and locally specified materials often use different measurement systems.
8Which measuring instrument is most appropriate for accurately measuring the diameter of a thin conductor wire in fractions of a millimeter?
A.Steel measuring tape
B.Micrometer screw gauge
C.Spirit level
D.Try square
Explanation: A micrometer screw gauge is designed to measure very small dimensions precisely, down to fractions of a millimeter, making it suitable for checking thin conductor diameters. A steel tape lacks this level of precision.
9A job sheet specifies a hole diameter of "10 mm ± 0.5 mm." What is the smallest acceptable diameter for the finished hole?
A.9.5 mm
B.10.5 mm
C.10 mm
D.9 mm
Explanation: The tolerance ± 0.5 mm means the finished diameter may range from 10 - 0.5 = 9.5 mm up to 10 + 0.5 = 10.5 mm. Understanding tolerance ranges prevents rejecting acceptable work or accepting out-of-spec work.
10A wiring job requires four separate circuit runs of 3.5 m, 4.2 m, 2.8 m, and 5.0 m. If 10% extra length must be added for jointing and wastage, approximately how much cable should be purchased?
A.15.5 m
B.17.05 m
C.19.5 m
D.20.0 m
Explanation: Adding the four runs gives 3.5 + 4.2 + 2.8 + 5.0 = 15.5 m. Adding 10% for jointing and wastage gives 15.5 × 1.10 = 17.05 m, so the electrician should purchase approximately that amount of cable.

About the BTEB Electrician (EIM) Exam Exam

The BTEB National Skill Certificate in Electrical Installation and Maintenance (EIM), NTVQF Level-I, certifies competence in basic electrical installation and maintenance work in Bangladesh. The 12 units of competency cover basic mathematics, OSH, teamwork and the construction sector, using electrical tools, fundamental electrical skills (materials, drawing symbols, current and voltage measurement), wire and cable joints, circuit connections, installing electrical circuits, fittings, channel wiring and fan installation, alongside a hands-on practical assessment.

Assessment

Competency-Based Training & Assessment (CBT&A) under the NTVQF, combining knowledge checks (written and oral questioning) with a supervised practical demonstration for each of the 12 units of competency, administered by BTEB through affiliated technical institutes. The full NSC-I curriculum totals 360 nominal training hours.

Time Limit

Set by BTEB and the registered assessment centre for each unit of competency. Confirm exact timing with your institute.

Passing Score

NTVQF assessment is competency-based: candidates are graded "Competent" or "Not Yet Competent" against the published standard for each unit rather than a single percentage score. Confirm the exact assessment method with your assessment centre.

Exam Fee

Registration and assessment fees are set by BTEB and the enrolling institute and are government-subsidised but change periodically. Confirm the current amount with your institute. (Bangladesh Technical Education Board (BTEB))

BTEB Electrician (EIM) Exam Study Tips from Top Performers

1Learn the four basic wire and cable joints (pigtail, western union, T-joint and married joint) by their specific use case, since exam questions often test which joint fits which situation rather than just the twisting technique.
2Pair each theory topic with hands-on practice in the workshop, such as stripping and joining a test wire, wiring a two-way switch circuit, or hanging a ceiling fan, since BTEB's CBT&A model assesses practical competence alongside knowledge.
3Always observe OSH procedure and use the correct tool for each job, for example an insulated screwdriver near live parts, a line tester before touching a conductor, and a soft-faced hammer for rawl plugs, since safe and correct tool use is directly assessed.
