Question 1 · 1 mark · Difficulty 1/3

In a series circuit containing three resistors, what happens to the current as it flows from one resistor to the next?

  1. A) It increases at each resistor
  2. B) It decreases at each resistor
  3. C) It remains the same throughout
  4. D) It depends on the value of each resistor
Show answer & explanation
✓ Answer: CC) It remains the same throughout
In a series circuit, there is only one path for current to flow, so the same current passes through every component. This is a fundamental property of series circuits and is independent of individual resistor values.
Question 2 · 1 mark · Difficulty 2/3

Three resistors of 4 Ω, 6 Ω, and 2 Ω are connected in series to a 24 V battery. What is the current flowing through the circuit?

  1. A) 0.42 A
  2. B) 2 A
  3. C) 4 A
  4. D) 12 A
Show answer & explanation
✓ Answer: BB) 2 A
The total resistance in a series circuit is the sum of individual resistances: 4 + 6 + 2 = 12 Ω. Using Ohm's Law, I = V/R = 24/12 = 2 A. The same 2 A flows through every resistor in the series circuit.

CXC CSEC Physics: Series and Parallel Circuits: Current, Voltage and Resistance FAQ

How many CXC CSEC Physics questions on Series and Parallel Circuits: Current, Voltage and Resistance are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Series and Parallel Circuits: Current, Voltage and Resistance 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 Series and Parallel Circuits: Current, Voltage and Resistance 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 Series and Parallel Circuits: Current, Voltage and Resistance 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 Series and Parallel Circuits: Current, Voltage and Resistance typically tested on CXC CSEC Physics papers?
Series and Parallel Circuits: Current, Voltage and Resistance 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.
