Year 10 Science: Electricity and Magnetism Flash cards /Vocab

What is an ammeter used for?

An ammeter is used to measure electric current in amperes.

What is the unit of electric current?

Ampere (Amps) is the unit of electric current.

What is the difference between attraction and repulsion in magnetism?

Attraction occurs between opposite poles of magnets, while repulsion occurs between like poles.

What is a battery?

A battery is a device that stores electrical energy and provides power to a circuit.

What is the purpose of a bulb in an electrical circuit?

A bulb converts electrical energy into light energy.

What is a cell in the context of electricity?

A cell is a single electrochemical unit that generates electrical energy.

What is electric charge?

Electric charge is a property of particles that causes them to experience a force in an electric field.

What is a circuit?

A circuit is a closed loop that allows electric current to flow.

What is a conductor?

A conductor is a material that allows electric current to pass through it easily.

What is current?

Current is the flow of electric charge, measured in amperes.

What is electrical energy?

Electrical energy is the energy derived from electric potential energy or kinetic energy of charged particles.

What is an electromagnet?

An electromagnet is a type of magnet created by electric current.

What is an electron?

An electron is a subatomic particle with a negative charge.

What is energy in the context of electricity?

Energy is the capacity to do work, often measured in joules.

What is an insulator?

An insulator is a material that resists the flow of electric current.

What are kilowatts and watts?

Kilowatt is a unit of power equal to 1,000 watts.

What is a kilowatt-hour?

A kilowatt-hour is a measure of electrical energy equivalent to one kilowatt of power used for one hour.

What is a magnet?

A magnet is an object that produces a magnetic field.

What is a magnetic field?

A magnetic field is the region around a magnet where magnetic forces can be detected.

What is magnetism?

Magnetism is a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces.

What is the difference between parallel and series circuits?

In a parallel circuit, components are connected across common points, while in a series circuit, components are connected end-to-end.

What is power in electrical terms?

Power is the rate at which electrical energy is transferred by an electric circuit, measured in watts.

What is static electricity?

Static electricity is the accumulation of electric charge on the surface of objects.

What are volts and voltage?

Volts are the unit of electric potential difference, also known as voltage.

What is a voltmeter used for?

A voltmeter is used to measure the voltage across two points in a circuit.
