Question 1 · 1 mark · Difficulty 1/3

What is the SI unit of electric current?

  1. volt
  2. ampere
  3. ohm
  4. coulomb
Show answer & explanation
✓ Answer: Bampere
Award 1 mark for identifying the ampere (A) as the SI unit of electric current. A is incorrect — the volt is the unit of potential difference. C is incorrect — the ohm is the unit of resistance. D is incorrect — the coulomb is the unit of electric charge.
Question 2 · 1 mark · Difficulty 1/3

A light-dependent resistor (LDR) is used in a street lighting system in Singapore. What happens to the resistance of the LDR as daylight decreases?

  1. The resistance decreases
  2. The resistance increases
  3. The resistance stays the same
  4. The resistance first increases then decreases
Show answer & explanation
✓ Answer: BThe resistance increases
Award 1 mark for correct identification. As light intensity decreases, the resistance of an LDR increases. A is incorrect — this describes what happens when light intensity increases. C is incorrect — LDR resistance varies with light intensity. D is incorrect — there is no reversal in the relationship.

CIE IGCSE Physics: Electric current and circuit components FAQ

How many CIE IGCSE Physics questions on Electric current and circuit components are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Electric current and circuit components for CIE IGCSE 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 CIE 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 CIE IGCSE 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 Electric current and circuit components practice with other Physics topics or even switch to a totally different CIE 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 Electric current and circuit components questions aligned to the official CIE IGCSE Physics syllabus?
Every question is written against the published CIE IGCSE Physics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CIE 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 CIE.
How is Electric current and circuit components typically tested on CIE IGCSE Physics papers?
Electric current and circuit components appears across multiple question types on real CIE IGCSE 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.
