Question 1 · 1 mark · Difficulty 2/3

Which is an example of an ohmic conductor (at constant temperature)?

  1. A fixed resistor
  2. A filament lamp
  3. A diode
  4. A thermistor
Show answer & explanation
✓ Answer: AA fixed resistor
A fixed resistor at constant temperature is ohmic. Filament lamps, diodes and thermistors are non-ohmic.
Question 2 · 1 mark · Difficulty 2/3

An ohmic conductor at constant temperature has a current that is:

  1. Directly proportional to the potential difference
  2. Inversely proportional to the PD
  3. Independent of the PD
  4. Always zero
Show answer & explanation
✓ Answer: ADirectly proportional to the potential difference
For an ohmic conductor at constant temperature, current is directly proportional to PD, so resistance is constant.

AQA GCSE Physics: Resistance and Ohm's Law FAQ

How many AQA GCSE Physics questions on Resistance and Ohm's Law are there on Kramizo?
Kramizo currently has 15 exam-board-aligned practice questions on Resistance and Ohm's Law for AQA GCSE 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 AQA 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 AQA GCSE 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 Resistance and Ohm's Law practice with other Physics topics or even switch to a totally different AQA 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 Resistance and Ohm's Law questions aligned to the official AQA GCSE Physics syllabus?
Every question is written against the published AQA GCSE Physics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real AQA 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 AQA.
How is Resistance and Ohm's Law typically tested on AQA GCSE Physics papers?
Resistance and Ohm's Law appears across multiple question types on real AQA GCSE 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.
