FAD1022 Exam Tips — WhatsApp Voice Notes
Last-minute exam tips sourced directly from the lecturer via student WhatsApp group (Adian Sani and others), dated 2026-05-04. Annotated with lecturer and topic mappings. Authored by the lecturer — treated as first-party marking guidance.
Raw Transcript
How to increase the work function — we cannot just give the factor. Increase or decrease, our answer must have increase or decrease. For example, how to increase the threshold frequency.
If velocity selector, we must write the formula first. That's one mark.
Final exam: 3 sections, 3 hours. A, B and C.
A is 15 marks, consists of C2 and C3. C2 is fundamental, like define, state, or explain.
All A is only 3 marks. No matter what: 1 formula, 1 substitution, 1 final answer WITH correct unit.
If explanation — if it's asking for photoelectric condition: E must equal to work function. There's 3 factors. Must be metal.
Phasor Diagram will be drawn from X_C, X_L. Bahagian A is done.
For B, the question will be everything. Before midsem and after midsem question. Usually after midsem is Bahagian C. The lecturer will mark everything.
Take note of Electromagnetism, Tutorial 8 — most likely come out from there. Conductor Wire cases?
Every year magnetism will come out. For electromagnetism: velocity selector, induced current and emf.
Induction is easy, incredibly straightforward, transformer question.
Even though it's easy, a lot of students don't get full marks because of answering technique.
When there's increase/decrease question...
For semiconductor, be careful — semicon and electronics. Dr Zainal who teaches this is insanely strict with his marking. It's insanely hard to get 12/12 because of how strict his marking is. His question will ask a lot about explanation. When there's explanation, look at Tutorial 13.
When there's equivalent circuit: WRITE DIRECTION OF CURRENT! No matter op-amps, diode, transistor — it's mandatory for direction of current.
One more for op-amp: they'll ask to draw circuit. What'll happen when the op-amp value is high, and whether it'll work.
One more, for tutorial semiconductor: Tutorial 13 and Tutorial 12, look at the graph.
For Dr Zainal's part, Q-point? Operating system of the circuit? Use the lecture notes, one to one. It must follow his script one to one in the lecture notes. The question is like this about Q-point:
When the question asks to find all the values, justify the value, explain the value. For those questions, you must know what the question is all about. You need to find the Q-point.
> We discovered that the transistor is BARELY ON.
> I_s is very small — 0.093 mA — and most of the voltage VCC (14.5 V out of 16 V) is still across the transistor itself.
> This means it's sitting in the active region, ready to amplify a signal.
You must have a sort of storyline. That's how you need to answer Dr Zainal's question. The same with Miss Nurul Izzati's questions.
For nuclear physics, the question has derivation. You must do derivation.
For Miss Nurul Izzati: she'll do photoelectric and photon momentum.
Focus more on resonant frequency and phasor diagram.
What is the relationship of current with X_C — that's how Miss Nurul Izzati's question.
For electrostatics, there's potential. For electrostatic force, it's easy but confusing. The potential at centre, and whether it'll cancel. Take note of what was in the tutorials.
For capacitor, past year students used to say it was hard. Capacitor high critical thinking, charging and discharging. 80% or something.
For DC analysis, Kirchhoff — a lot of Kirchhoff. It's a very long writing. You must know how to use KVL and KCL. Kirchhoff current law is very important. Something about simultaneous equations? They'll give loop, and you must follow the loop — positive and negative.
What are conditions for photoelectric?
Phasor diagram drawing.
Tutorial 8 Q2.
Magnetism.
EM: velocity selector, detected induced current.
How to increase efficiency of transformer.
ALWAYS DO THE DIRECTION OF CURRENT.
Tutorial 13.
Tutorial 12.
Drawing question.
Q-point?
Photoelectric effect.
Focus on resonance frequency.
Photon momentum.
Electrostatic potential.
Confusing? It's like asking potential.
Revise Tutorial 1 and 2.
Capacitor has HOT — charging and discharging.
DC analysis: positive or negative?
Loop and Kirchhoff.
EXPLAIN TRANSFORMERS.
DO Tutorial 1 and 2.
Electrostatic just calculations.
