Physics-Electricity Flashcards
To learn about electricity and magnetism
What are the three main charges a atom can possess:
- Postive
- Negiative
- Neutral
What are the three main charge rules?
- Opposite attract
- Like repel
- Neutral do nothing
What charge are:
* Electrons
* Protons
* Neutrons
- Negiative
- Postive
- Neutral
Define
Static electricty
A build-up of electrical charge on an object, which can be either positive or negative.
Define
Electric Current
An electric current is a flow of charged particles in one direction. In solids, an electric current is the flow of free electrons in one direction.
Define
Electric Circuit
An electrical circuit is made up of components, which are connected together using wires.When currents are put into a loop, with a battery pushng it around
Define
Components
A part of a circuit
Eg. A battery, motor, lamp, switch or wire.
Define
Volts
How much electrical energy each atom possess in a part of the circuit.
Define
Amps
How much charge passes a specifc point in a second
differencee betweeen
- Series
- Parrell
- One loop circuit
- Multi-loop circuit
Define
AC current
A current that can be alternated(switch dierection) with the use of electromagnets
Define
DC current
A current that is one-way but far more powerful
