1A balanced 480-volt, three-phase load draws 65 amperes at a lagging power factor of 0.88. What is the real power of this load?
A.27.5 kW
B.47.6 kW
C.54.1 kW
D.62.4 kW
Explanation: Three-phase real power is P = 1.732 × V × I × PF. Substituting gives 1.732 × 480 × 65 × 0.88 = 47,554 W, or 47.6 kW. Apparent power without the power factor is 54.1 kVA and is not the real-power answer.
2A 120-volt, single-phase, 2-wire branch circuit supplies an 18-ampere load. The one-way conductor length is 90 feet of 12 AWG copper (K = 12.9, area = 6,530 CM). What is the calculated voltage drop?
A.3.20 volts
B.5.55 volts
C.6.40 volts
D.10.51 volts
Explanation: Single-phase voltage drop is VD = (2 × K × I × L) / CM. Substituting gives (2 × 12.9 × 18 × 90) / 6,530 = 41,796 / 6,530 = 6.40 V. That is 5.3 percent of 120 V, above the 2017 NEC 210.19(A) Informational Note 4 three-percent branch-circuit recommendation.
3A series 60 Hz circuit has 8 ohms of resistance, 15 ohms of inductive reactance, and 9 ohms of capacitive reactance. What is the impedance of the circuit?
A.6.0 ohms
B.10.0 ohms
C.16.6 ohms
D.32.0 ohms
Explanation: Series impedance is Z = √(R² + (XL − XC)²). Net reactance is 15 − 9 = 6 ohms, so Z = √(8² + 6²) = √(64 + 36) = √100 = 10.0 ohms.
4A resistive heater rated 240 volts has a hot resistance of 16 ohms. What current does it draw at rated voltage?
A.0.067 ampere
B.15 amperes
C.256 amperes
D.3,840 amperes
Explanation: Ohm's law is I = E / R. 240 V / 16 Ω = 15 A. Power would be 240 × 15 = 3,600 W, but the question asks for current only.
5A 60 Hz sine-wave voltage has a peak value of 170 volts. What is the approximate RMS value?
A.85 volts
B.108 volts
C.120 volts
D.240 volts
Explanation: For a sine wave, RMS = peak / √2, or peak × 0.707. 170 / 1.414 ≈ 120 V. That is the everyday 120-volt RMS utilization voltage.
6Under the 2017 NEC, a grounded circuit conductor 6 AWG or smaller shall generally be identified by which means?
A.Green insulation or green with yellow stripes only
B.A continuous white or gray outer finish, or three continuous white or gray stripes
C.Orange insulation on all voltages above 150 volts to ground
D.Bare copper only, with no insulated option
Explanation: 2017 NEC 200.6(A) requires 6 AWG or smaller grounded conductors to be identified by a continuous white or gray finish, or by three continuous white or gray stripes on other-than-green insulation. Green is reserved for grounding, not the grounded (neutral) conductor.
7One mechanical horsepower is equal to which electrical power value?
A.746 watts
B.1,000 watts
C.550 watts
D.1,200 watts
Explanation: By definition used throughout Ugly's and the American Electrician's Handbook, 1 hp = 746 W. Motor input is larger than 746 W per horsepower because efficiency and power factor are less than 100 percent.
8Two 20-ohm resistors are connected in parallel. That combination is connected in series with a 10-ohm resistor. What is the total resistance?
A.10 ohms
B.15 ohms
C.20 ohms
D.50 ohms
Explanation: Two equal 20-ohm resistors in parallel equal 10 ohms (20 / 2). Adding the series 10-ohm resistor gives 10 + 10 = 20 ohms.
9What is the full-load line current of a 75 kVA, 480-volt, three-phase transformer?
A.90 amperes
B.156 amperes
C.52 amperes
D.78 amperes
Explanation: Three-phase line current is I = (kVA × 1000) / (V × 1.732). 75,000 / (480 × 1.732) = 75,000 / 831.4 = 90.2 A, typically taken as 90 A on contractor exams.
10A three-phase motor delivers 36 kW of real power while drawing 48 kVA. What is the power factor?
A.0.67
B.0.75
C.0.80
D.1.33
Explanation: Power factor is PF = P / S = 36 kW / 48 kVA = 0.75 lagging if the motor is inductive. It is a ratio and has no unit.

About the TN CE Electrical Exam

The Tennessee Electrical (CE) Contractor Examination is the official Board trade examination administered by Prov beginning July 1, 2026. The official exam has 100 questions. Passing is 73% in 5 hours. The examination is open book. Prov lists USD 53 per attempt (Tennessee Contractor Candidate Information Bulletin dated 2026.07.13). CE covers premises wiring, services, feeders, branch circuits, grounding, motors, communications, special occupancies, and OSHA safety under the 2017 NEC. Candidates must also pass Business and Law. The Board charges a separate USD 250 initial application fee. This bank is an English-language MCQ study adaptation. It does not replace required trade experience, board approval, financial statements or bonds, or the official examination.

Assessment

Open-book computer-based multiple-choice. Prov lists NFPA 70 National Electrical Code 2017, Ugly's Electrical References (2020), OSHA 29 CFR 1926, and the American Electrician's Handbook, 17th Edition. Remote Examroom testing is available.

Frequently Asked Questions

How many questions are on the Tennessee CE Electrical Contractor Examination?

The official Prov examination has 100 questions. Passing is 73% within 5 hours (Tennessee Contractor Candidate Information Bulletin dated 2026.07.13).

Which electrical code is used on the Tennessee CE exam?

Prov lists NFPA 70 — National Electrical Code, 2017 edition as the primary code reference for the CE examination.

Is the Tennessee CE exam the same as the Limited Licensed Electrician exam?

No. CE is the contractor electrical classification. Limited Licensed Electrician (LLE) is a separate Board program with its own examination and does not authorize acting as a contractor.

Do I also need the Business and Law exam?

Yes. Every new contractor applicant must pass the Tennessee Contractor Business and Law Examination in addition to any required trade examination.
