Question 1 · 1 mark · Difficulty 1/3

Which of the following correctly states Ohm's Law?

  1. A. The current through a conductor is inversely proportional to the potential difference across it at constant temperature.
  2. B. The potential difference across a conductor is directly proportional to the current through it at constant temperature.
  3. C. The resistance of a conductor increases proportionally with the current through it.
  4. D. The power dissipated in a conductor is directly proportional to the current through it.
Show answer & explanation
✓ Answer: B — B. The potential difference across a conductor is directly proportional to the current through it at constant temperature.
Ohm's Law states that the potential difference (V) across a conductor is directly proportional to the current (I) through it, provided temperature and other physical conditions remain constant. This gives the relationship V = IR. Options A, C, and D misrepresent the law.
Question 2 · 1 mark · Difficulty 1/3

A resistor has a potential difference of 12 V across it and a current of 3 A flowing through it. What is its resistance?

  1. A. 36 Ω
  2. B. 15 Ω
  3. C. 4 Ω
  4. D. 0.25 Ω
Show answer & explanation
✓ Answer: C — C. 4 Ω
Using Ohm's Law, R = V/I = 12/3 = 4 Ω. Option A results from multiplying V and I, option D from dividing I by V, and option B from adding V and I — all common student errors.

CXC CSEC Physics: Electricity FAQ

How many CXC CSEC Physics questions on Electricity are there on Kramizo?
Kramizo currently has 216 exam-board-aligned practice questions on Electricity for CXC CSEC Physics, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CXC paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CXC CSEC students preparing for Physics?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Electricity practice with other Physics topics or even switch to a totally different CXC subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Electricity questions aligned to the official CXC CSEC Physics syllabus?
Every question is written against the published CXC CSEC Physics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CXC.
How is Electricity typically tested on CXC CSEC Physics papers?
Electricity appears across multiple question types on real CXC CSEC Physics papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
