ELECTRICITY - Coggle Diagram
ELECTRICITY
Electrical Forces and Charges
Fundamental Rule: Like charges repel. Opposite charges attract
Neutral atom- no net charge
Ion- charged atom
Cation- has net positive charge
Anion - has net negative charge
Conductors
materials through which electric charge can flow
Gold
Seawater
Silver
Copper
Insulators
materials that impede the free flow of electrons
Rubber
Plastic
Glass
Wood
Electric Charge Transfer
Charging by Contact
Charging by Induction
Charging by Friction
Circuits
any path where electrons can flow
Types
Series Circuit
forms a single path for current flow
When one device fails, the current in the whole circuit stops.
Parallel Circuit
electric current has multiple paths to flow through
A break in one path does not interrupt the flow of charge in the other paths.
Ohm's Law
V=IR
I - Current
R - Resistance
V - Voltage
