Question 1 · 1 mark · Difficulty 1/3

What is the function of a fuse?

  1. To increase current
  2. To protect a circuit by melting if the current exceeds a safe value
  3. To store energy
  4. To measure voltage
Show answer & explanation
✓ Answer: BTo protect a circuit by melting if the current exceeds a safe value
A fuse contains a thin wire that melts and breaks the circuit if the current is too high, protecting the device and wiring from overheating or fire.
Question 2 · 1 mark · Difficulty 1/3

What is the difference between AC and DC?

  1. They are the same
  2. AC periodically changes direction; DC flows in one direction only
  3. DC changes direction
  4. AC comes from batteries
Show answer & explanation
✓ Answer: BAC periodically changes direction; DC flows in one direction only
AC (alternating current) constantly reverses direction — used in mains electricity. DC (direct current) flows in one direction only — produced by batteries and cells.

CXC CSEC Physics: Current Electricity FAQ

How many CXC CSEC Physics questions on Current Electricity are there on Kramizo?
Kramizo currently has 16 exam-board-aligned practice questions on Current 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 Current 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 Current 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 Current Electricity typically tested on CXC CSEC Physics papers?
Current 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.
