Uses and Dangers of Static Electricity — exam questions
12 original Incandio exam-style questions on Uses and Dangers of Static Electricity, 28 marks, about 28 minutes of writing. Each one carries the command word, the tariff and the specification statement it assesses, exactly as a paper presents them. This is an original Incandio practice question, written to reflect the structure and demands of the qualification. It is not an official Pearson Edexcel past-paper question.
This is the practice set for Uses and Dangers of Static Electricity — the lesson that teaches it. Read the lesson first if the idea is new; come here when you want to find out whether you can turn it into marks. Completely free, no account needed to read.
What these questions ask of you
7 command words run through this set, and on Pearson Edexcel International GCSE Physics each one means something precise. Answering the wrong command is the commonest way a candidate who understands the lesson still loses the mark.
- Which (1 mark)
- one option chosen from the set given
- Give (1–2 marks)
- a short factual answer
- Name (1 mark)
- the correct quantity, unit or component
- Describe (2–4 marks)
- developed, linked statements of what happens — including a named direction where one exists
- Explain (2–4 marks)
- the physics that causes it, set out as a line of reasoning Misread as: describing the change without giving the physical reason for it
- Suggest (1–3 marks)
- a plausible answer applying taught physics to an unfamiliar arrangement
- Complete (1–4 marks)
- the missing entries in a table, circuit or diagram
Assessed on Paper 1 (4PH1/1P) and Paper 2 (4PH1/2P), against AO1, AO2, AO3.
Where these sit in the specification
Pearson Edexcel International GCSE Physics (4PH1) — statements 2.28 · 2.27 · 2.26. Incandio is aligned to this specification; it is not published by, endorsed by or affiliated with Pearson, and it reproduces none of Pearson's wording.
The 12 questions
Answer them on paper, then open the lesson's exam practice to have them marked. The mark scheme, the accepted and rejected answers and the annotated model answer are in Incandio and are not printed here — an answer beside its question is not practice.
-
Table 1 — four situations involving static electricity Situation Use or danger Why refuelling an aircraft danger a spark could ignite the fuel vapour a photocopier use charged toner sticks to the charged image an inkjet printer use charged droplets are steered by charged plates a lorry delivering flour to a mill to be found a spark could ignite the flour dust (a)
(1)Complete
Complete Table 1 by classifying the flour delivery as a use or a danger.
Table 1 — four situations involving static electricity Situation Use or danger Why refuelling an aircraft danger a spark could ignite the fuel vapour a photocopier use charged toner sticks to the charged image an inkjet printer use charged droplets are steered by charged plates a lorry delivering flour to a mill to be found a spark could ignite the flour dust (b)
(2)Explain
Explain what the two dangerous situations in Table 1 have in common that the two uses do not.
Table 1 — four situations involving static electricity Situation Use or danger Why refuelling an aircraft danger a spark could ignite the fuel vapour a photocopier use charged toner sticks to the charged image an inkjet printer use charged droplets are steered by charged plates a lorry delivering flour to a mill to be found a spark could ignite the flour dust (c)
(3)Explain
Explain, in terms of charge, how the photocopier in Table 1 gets the toner onto the right part of the page.
Table 1 — four situations involving static electricity Situation Use or danger Why refuelling an aircraft danger a spark could ignite the fuel vapour a photocopier use charged toner sticks to the charged image an inkjet printer use charged droplets are steered by charged plates a lorry delivering flour to a mill to be found a spark could ignite the flour dust (d)
(3)Suggest
Suggest one precaution for the flour delivery in Table 1, and explain why it works.

-
(1)Which
Which device uses static electricity to place ink or toner accurately?
Device A a kettle B a photocopier C a transformer D a fuse (Total for Question 2 = 1 mark)
-
(1)Give
Give one situation in which a build-up of static charge is dangerous.
(Total for Question 3 = 1 mark)
-
(1)Name
Name the precaution taken to stop static charge building up on a fuel tanker.
(Total for Question 4 = 1 mark)
-
(3)Describe
Describe how a person walking on a nylon carpet can receive a shock from a metal door handle.
(Total for Question 5 = 3 marks)
-
(3)Explain
Explain why static electricity is particularly dangerous when an aircraft is being refuelled.
(Total for Question 6 = 3 marks)
-
(3)Explain
Explain how an inkjet printer uses static charge to place droplets accurately on the paper.
(Total for Question 7 = 3 marks)
-
(3)Suggest
Suggest why electrostatic spray painting coats the back of a car panel as well as the front.
Electrostatic spray painting — In an electrostatic spray gun every paint droplet is given the same charge as it leaves the nozzle. The metal panel being painted is given the opposite charge. The droplets are far too light for gravity to determine their path over the short distance involved.
(Total for Question 8 = 3 marks)
-
(4)Explain
Explain why a tanker delivering fuel is connected to the ground by a metal strap before the fuel is pumped out.
(Total for Question 9 = 4 marks)
Have them marked, then defend the answer
Practice tells you the mark; teaching it back tells you whether you understand it. On Incandio a topic counts as mastered only once you have taught it and defended it.
- Mark these questions — 12 questions, marked on Incandio against the authored scheme, with the mistake you actually made named.
- Teach it — explain Uses and Dangers of Static Electricity to Ember, an AI pupil who does not have it yet and asks the awkward question.
- Defend it — argue it against Benjamin Franklin over three rounds, marked against descriptors you can read first.
