Question 1 · 1 mark · Difficulty 1/3

A technician in a Jamaican electronics repair shop connects three resistors of 2 Ω, 3 Ω, and 5 Ω in series. What is the total resistance of the circuit?

  1. 0.97 Ω
  2. 10 Ω
  3. 30 Ω
  4. 1.03 Ω
Show answer & explanation
✓ Answer: B10 Ω
Award 1 mark for correct calculation using R_total = R₁ + R₂ + R₃ = 2 + 3 + 5 = 10 Ω. A is incorrect — this is the result of calculating parallel resistance. C is incorrect — this multiplies the resistances. D is incorrect — this confuses the formula with parallel combination.
Question 2 · 1 mark · Difficulty 1/3

Which statement correctly describes the current in a series circuit?

  1. The current is different at each resistor
  2. The current is the same through each resistor
  3. The current increases after each resistor
  4. The current is zero between resistors
Show answer & explanation
✓ Answer: BThe current is the same through each resistor
Award 1 mark for identifying that in a series circuit, there is only one path for current flow, so current remains constant throughout. A is incorrect — this describes parallel circuits. C is incorrect — current does not increase as it passes through resistors. D is incorrect — current flows continuously through all components.

CXC CSEC Physics: Resistors in Series and Parallel Circuits FAQ

How many CXC CSEC Physics questions on Resistors in Series and Parallel Circuits are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Resistors in Series and Parallel Circuits 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 Resistors in Series and Parallel Circuits 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 Resistors in Series and Parallel Circuits 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 Resistors in Series and Parallel Circuits typically tested on CXC CSEC Physics papers?
Resistors in Series and Parallel Circuits 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.
