Electrical Principles Topic 1 Flashcards
The 3 laws of electrical charge
- Opposite charges attract
- Like charges repel
- Charged objects attract neutral objects
Define electrostatic charge
The charge of an ion
What is friction
the transfer of electron between objects
what is charge separation
It occurs when a charged object is brought close to a neutral object
What is static electricity
Happens when there is an imbalance of electrons between two objects
What is electrical discharge
The movement of charges from one object to the other
What is current
The flow of electricity
What are Amperes
Measures the rate at which the electricity is flowing
What is the difference between static and current electricity
Current is steady flow, static is the rapid discharge of electrons
What is voltage
How much energy an individual charged particle has
What is the purpose of a fuse or circuit breaker
To interrupt a circuit if there is too much current flowing through it
Define dry cell
A paste is used to produce electricity
Define wet cell
A liquid is used to produce electricity
