Coverage includes Ohm's Law, machines, control equipment, test instruments, RA 7920 RME rules, and PEC wiring, protection, and safety requirements.

Sample RME Board Exam Practice Questions

Try these sample questions to test your RME Board Exam exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 200+ question experience with AI tutoring.

1A resistive load draws 5 A from a 120 V DC source. What is the resistance of the load?

A.24 Ω

B.20 Ω

C.600 Ω

D.0.042 Ω

Explanation: Ohm's Law states R = V/I. Dividing 120 V by 5 A gives 24 Ω. Master electricians use this relationship constantly when sizing resistors, heaters, and verifying measured loads.

2A 2.0 kW heater operates continuously on 220 V AC. Approximately what current does it draw?

A.4.5 A

B.9.1 A

C.11 A

D.440 A

Explanation: Power P = V × I for a resistive load, so I = P/V = 2000 W / 220 V ≈ 9.09 A. Rounding to 9.1 A is appropriate for practical sizing and measurement checks.

3Three identical 30 Ω resistors are connected in parallel across a 90 V source. What is the total current drawn from the source?

A.1 A

B.3 A

C.9 A

D.10 A

Explanation: Each parallel branch carries I = V/R = 90/30 = 3 A. Three identical branches draw 3 × 3 = 9 A total. Parallel resistors share the same voltage, so branch currents add.

4In a purely resistive AC circuit, which statement is correct?

A.Current leads voltage by 90°

B.Current lags voltage by 90°

C.Power factor is always zero

D.Voltage and current are in phase

Explanation: In a purely resistive circuit, voltage and current reach peaks and zeros together, so they are in phase and the power factor is 1.0. Inductive circuits lag and capacitive circuits lead.

5A series circuit contains a 12 Ω resistor and a 16 Ω inductive reactance at 60 Hz. What is the impedance magnitude?

A.20 Ω

B.4 Ω

C.28 Ω

D.192 Ω

Explanation: Series impedance Z = √(R² + X_L²) = √(12² + 16²) = √(144 + 256) = √400 = 20 Ω. This 3-4-5 relationship is a common exam shortcut for RL series circuits.

6A single-phase motor draws 8 A at 230 V with a power factor of 0.80. What is the approximate real power input?

A.1.84 kW

B.1.47 kW

C.2.30 kW

D.2.94 kW

Explanation: Real power P = V × I × pf = 230 × 8 × 0.80 = 1472 W ≈ 1.47 kW. Apparent power would be V × I = 1.84 kVA, which is larger than real power when pf < 1.

7Two resistors of 10 Ω and 40 Ω are connected in series across 100 V. What voltage appears across the 40 Ω resistor?

A.20 V

B.40 V

C.80 V

D.100 V

Explanation: Series current I = 100/(10+40) = 2 A. Voltage across 40 Ω is I × R = 2 × 40 = 80 V. Voltage divides in proportion to resistance in a series circuit.

8For a balanced three-phase wye (star) load, the line voltage is related to the phase voltage by which factor?

A.Line voltage equals phase voltage

B.Line voltage = 3 × phase voltage

C.Line voltage = phase voltage / √3

D.Line voltage = √3 × phase voltage

Explanation: In a balanced wye system, V_L = √3 × V_ph because line-to-line voltage spans two phase windings with 120° separation. Phase current equals line current in wye.

9A 480 V, three-phase balanced load draws 20 A line current at a power factor of 0.90. Approximately what is the three-phase real power?

A.15.0 kW

B.8.3 kW

C.9.0 kW

D.17.3 kW

Explanation: Three-phase real power P = √3 × V_L × I_L × pf = 1.732 × 480 × 20 × 0.90 ≈ 14,964 W ≈ 15.0 kW. Omitting √3 is a common calculation error.

10If the frequency of an AC supply doubles while inductance stays constant, inductive reactance X_L will:

A.Halve

B.Double

C.Remain the same

D.Increase by a factor of four

Explanation: Inductive reactance X_L = 2πfL is directly proportional to frequency. Doubling frequency doubles X_L when L is unchanged, which raises impedance of inductive loads.

About the RME Board Exam Exam

The Registered Master Electrician (RME) Licensure Examination is the written board exam administered by the PRC Board of Electrical Engineering under Republic Act No. 7920. It is typically held twice yearly in the same window as the REE exam and covers two equally weighted subject groups: Technical Subjects and Philippine Electrical Code Parts 1 and 2. The RME credential authorizes installation, wiring, operation, maintenance, and repair of electrical systems within the voltage and capacity limits set by RA 7920 (generally not exceeding 600 V and 500 kVA without REE/PEE supervision).

RME Board Exam Study Tips from Top Performers

1Split study time evenly: Technical Subjects and PEC each carry 50% of the rating

2Memorize key PEC rules used on RMELE notices: minimum branch conductors, continuous-load 125% sizing, and grounding basics

3Drill Ohm's Law and three-phase power formulas until calculations are automatic under time pressure

4Know motor starter types (DOL, star-delta, autotransformer) and the protective devices paired with them

5Review RA 7920 RME practice limits (600 V / 500 kVA) and license class distinctions (RME vs REE vs PEE)

6Practice reading one-line diagrams, panel schedules, and motor control wiring symbols

7Use a clamp meter, megger, and multimeter mentally in maintenance scenarios so instrument questions stay concrete

8Take timed mock exams that balance 50% technical and 50% code items in one sitting

Frequently Asked Questions

What is the passing score for the RME board exam?

Under RA 7920 Section 19, a Registered Master Electrician candidate must obtain a general average of at least 70% with no grade below 50% in any subject. The two subject groups are weighted Technical Subjects 50% and Philippine Electrical Code Parts 1 and 2 50%.

What subjects are covered in the RME licensure examination?

The RME exam covers Technical Subjects (Ohm's Law, electrical machines, control equipment, components, maintenance, test equipment, and RME law) and Philippine Electrical Code Parts 1 and 2 (installation requirements, wiring methods, materials and devices, panelboards, hazardous locations, motor-starter diagrams, and drawing symbols). Each group carries 50% weight.

How is the RME exam different from the REE exam?

The REE exam is for Registered Electrical Engineers and covers Mathematics (25%), Engineering Sciences and Allied Subjects (30%), and Professional Subjects (45%) over multiple days. The RME exam is for Registered Master Electricians, focuses on practical technical subjects plus the Philippine Electrical Code (50/50), and is designed to be finished in one eight-hour day.

How often is the RME licensure examination given?

The PRC Board of Electrical Engineering administers the RME exam twice a year, typically in the same examination window as the REE (commonly April and August/September). Confirm the exact dates on the PRC 2026 Schedule of Examinations.

What is the RME examination fee?

Per the PRC List of Requirements for Electrical Engineering, the examination payment is PHP 900 for a complete examination and PHP 450 for removal or conditioned subjects. Always confirm the current schedule of fees on the PRC website before filing.

What voltage and capacity limits apply to RME practice?

Under RA 7920, a Registered Master Electrician's field of practice includes installation, wiring, operation, maintenance, and repair of electrical machinery and devices. If the installation or machinery exceeds 500 kVA or 600 volts, the work must be under the supervision of a Professional Electrical Engineer or Registered Electrical Engineer.
