GCSE Physics 0625 Unit 4 - Electricity
& Magnetism Exam 2025/2026 With
100% Correct Answers
4.2 Electrical quantities CORRECT ANSWERS 4.2.1 - Electric
charge
4.2.2 - Electric current
4.2.3 - Electromotive force and potential difference
4.2.4 - Resistance
4.2.5 - Electrical Energy and electrical power
What is electric charge? CORRECT ANSWERS Electric charge
is the physical property of matter due to which it experiences a
force when place in an electric or magnetic field
Types of charge CORRECT ANSWERS Positive (+ve) and
Negative (-ve). Like (positive and positive) (negative and
negative) charges repel and unlike charges attract (positive and
negative).
SI unit of charge CORRECT ANSWERS Coulomb (C)
, Conductors and Insulators CORRECT ANSWERS Conductors
are materials which allow the electric current to pass through it
freely (Copper, silver, graphite etc.).
Insulators are materials which do not allow the electric current
pass through it. (Plastic, wood, dry air etc.)
Recall and use a simple electron model to explain the difference
between electrical conductors and insulators and give typical
examples CORRECT ANSWERS Conductors have a large
number of free delocalized electrons whereas insulators don't.
The movement of these electrons allows the charge to be
transferred in conductors.
Ways to charge a body or object CORRECT ANSWERS 1.
Friction
2. Induction
1. Friction CORRECT ANSWERS -When an object is rubbed
over another object, the electrons get transferred from one object
to another due to friction.
-The object which loses electrons becomes positively charged
while the object which gains the electrons becomes negatively
charged.
- this method only works in insulators.
