1The Laplace transform of e^{-at} u(t) is:

A.s/(s+a)

B.1/(s+a)

C.1/(s-a)

D.a/(s+a)

Explanation: By definition, L{e^{-at}u(t)} = ∫_0^∞ e^{-at}e^{-st} dt = 1/(s+a) for Re(s) > -a. The pole sits at s = -a.

2For a normal (Gaussian) random variable, approximately what percentage of outcomes lie within ±1 standard deviation of the mean?

A.About 99.7%

B.About 68%

C.About 50%

D.About 95%

Explanation: The empirical rule for a normal distribution assigns roughly 68% of probability mass to the interval μ ± σ, 95% to μ ± 2σ, and 99.7% to μ ± 3σ.

3For a 2×2 matrix [[a,b],[c,d]], the determinant equals:

A.ad + bc

B.ad − bc

C.ab − cd

D.ac − bd

Explanation: det([[a,b],[c,d]]) = ad − bc. This scalar governs invertibility (nonzero det) and appears in Cramer’s rule and eigenvalue products.

4The complex number 3 + j4 in polar form has magnitude:

A.1

B.5

C.7

D.12

Explanation: |3 + j4| = √(3² + 4²) = √(9+16) = 5. This is the same magnitude used for a 3-4-5 phasor in AC circuit analysis.

5In the Newton–Raphson method for finding a root of f(x)=0, the iterative update is:

A.x_{n+1} = x_n − f'(x_n)/f(x_n)

B.x_{n+1} = x_n − f(x_n)/f'(x_n)

C.x_{n+1} = x_n + f(x_n)/f'(x_n)

D.x_{n+1} = f(x_n)/f'(x_n)

Explanation: Newton–Raphson linearizes f about x_n: the tangent hits zero at x_n − f(x_n)/f'(x_n). Convergence is quadratic near a simple root when f' ≠ 0.

6A 12 V DC source drives a series combination of 4 Ω and 2 Ω resistors. The current in the loop is:

A.1 A

B.2 A

C.3 A

D.6 A

Explanation: Total resistance is 4+2=6 Ω. I = V/R = 12/6 = 2 A. Series current is the same through both resistors.

7Kirchhoff’s Current Law (KCL) states that at any node:

A.All branch currents must be equal

B.The algebraic sum of currents entering equals the algebraic sum leaving (net current is zero)

C.The sum of voltage drops equals the source voltage only in resistive loops

D.Power is conserved only in DC circuits

Explanation: KCL is charge conservation at a node: Σ I_in = Σ I_out, or equivalently Σ I = 0 with a consistent sign convention.

8Thévenin’s theorem replaces a linear network seen from two terminals by:

A.A voltage source in parallel with R_th

B.An equivalent voltage source V_th in series with R_th

C.An equivalent current source I_n in series with R_th

D.Only an equivalent resistance with no source

Explanation: Thévenin form is V_th in series with R_th. Norton form is the dual: I_n in parallel with R_n (where R_n = R_th and I_n = V_th/R_th).

9At angular frequency ω, the impedance of a capacitor C is:

A.R + jωC

B.1/(jωC)

C.jωC

D.jωL

Explanation: v = (1/C)∫i dt implies Z_C = 1/(jωC) = −j/(ωC). Capacitive reactance falls as frequency rises.

10In a series RLC circuit, resonance occurs when:

A.The source frequency is zero

B.X_L = X_C so the net reactance is zero

C.R = 0

D.X_L = R

Explanation: Series resonance is at ω_0 = 1/√(LC) where X_L = X_C, impedance is minimum and equal to R, and current is maximum for a given voltage.

PEC EPE Electrical Study Tips from Top Performers

1Weight Breadth study to circuits (20%), control/DSP (20%), and electronics (17%) before lighter 10% clusters

2Choose a Depth track that matches your daily practice (e.g., Electric Power for utility/protection work)

3Build a tabbed open-book kit early—Part-II rewards fast lookups of curves, vector groups, and code tables

4Practice timed 60-question sets in three hours to match Part-II pacing

5Keep Part-I (management, ethics, environment, hazards, communication) warm if attempting both parts the same day

6Confirm cycle dates, centres, and fee voucher rules on cpd.pec.org.pk before applying

7Log errors by syllabus outcome so retakes target weak Breadth or Depth clusters

8Only bring a simple calculator—programmable devices and phones are prohibited

Frequently Asked Questions

How many questions are on PEC EPE Electrical Part-II?

Part-II Electrical & Allied has 60 multiple-choice questions: 25 Breadth (Section A) plus 35 Depth in your opted specialization (Section B). The paper lasts three hours and is open-book for bound books and standards only.

What is the passing score for EPE Part-II?

You must score at least 60% in Part-II. Part-I and Part-II are passed independently; failing one part does not cancel a pass in the other within the allowed retake window.

What Breadth topics carry the most weight?

Per the official Electrical & Allied syllabus, Electric Circuits and Control Systems/Signal Processing are each 20% of Breadth, Electronics is 17%, Mathematics is 13%, and Electric Power Basics, Computer Fundamentals, and Analog/Digital Communication are each 10%.

Who is eligible to sit for the EPE?

A PEC Registered Engineer with at least five years of relevant practical experience since registration (to the announcement closing date) and at least 17 CPD credit points since 10 July 2010 or initial registration, whichever is later.

Is Part-II open book?

Yes. Part-II allows books and bound copies of standards/texts as described for the discipline. Loose notes, handouts, and electronic devices (except a simple calculator) are not permitted.

How is the EPE fee paid?

Fees are published on each cycle’s notice. Payment must be made through a Bank Alfalah system-generated voucher from the CPD portal; deposits by other methods are not accepted. Always confirm the current amount before paying.
