What is a series circuit?
It is a circuit that links components one after another, making one loop. This means all power is shared between the components.
What is a parallel circuit?
It is a circuit that links components in separate loops. This means that all the components are given all the potential energy.
What is a component?
A part in a circuit.
What is charge?
A positive or negative property of substances, that causes the substance to feel a force when there are other charges nearby.
What is a conductor?
A material that can carry an electrical current.
What is an insulator?
A material that doesn’t carry an electrical current.
What is friction?
A force that is created when two things move past each other.
What is potential difference? (or voltage)
It is the measure of the difference in electrical potential energy between two points.
What is static electricity?
Electrical charges that aren’t moving.
What are electrons?
Tiny, negatively charged particles found in all atoms.
What is resistance?
The property of materials that determines how much current they carry.
What is work?
The transfer of energy from one store to another.
Do conductors have high or low resistance?
Low, which is why they let charges flow through them.
What does an ammeter measure?
