Question 1 · 1 mark · Difficulty 1/3

In a series circuit containing two resistors, what happens to the current as it flows from the first resistor to the second resistor?

  1. A: It decreases because some current is used up by the first resistor
  2. B: It increases because the second resistor adds energy
  3. C: It remains the same throughout the circuit
  4. D: It splits equally between the two resistors
Show answer & explanation
✓ Answer: C — C: It remains the same throughout the circuit
In a series circuit, the current is the same at every point because there is only one path for the current to flow. Current is not 'used up' by resistors; it is the same throughout. The misconception that current decreases after each component is very common but incorrect.
Question 2 · 1 mark · Difficulty 1/3

Which of the following correctly describes how voltmeters and ammeters are connected in a circuit?

  1. A: Voltmeters in series; ammeters in parallel
  2. B: Voltmeters in parallel; ammeters in series
  3. C: Both voltmeters and ammeters in series
  4. D: Both voltmeters and ammeters in parallel
Show answer & explanation
✓ Answer: B — B: Voltmeters in parallel; ammeters in series
Voltmeters must be connected in parallel with the component being measured so they have negligible effect on the circuit (high resistance). Ammeters must be connected in series so all the current flows through them (low resistance). Connecting them the other way would short-circuit components or give zero readings.

CIE IGCSE Physics: Series and parallel circuits FAQ

How many CIE IGCSE Physics questions on Series and parallel circuits are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Series and parallel circuits 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 Series and parallel circuits 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 Series and parallel circuits 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 Series and parallel circuits typically tested on CIE IGCSE Physics papers?
Series and parallel circuits 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.
