Design and Tech - Electricity

Electricity

: The movement of electrons, an invisible force that provides light, heat, sound, and motion.

Resistors

= components that create - dims the light.

Electrons

flow out of negative ide of battery through circuit tend back to the positive side of battery.

Voltage

Ohms Law: = Resistance x Current or V= IR.

Electron Flow

is actually what happens.

Conventional Current

: assumes that current flows out of the positive side of the batter through the circuit and back to the negative side of the batter.

Elements

At the atomic level: : simplest form of matter.

Sum of all voltage drops

What is equal to the total applied voltage- V total= V1 + V2 + V3,

Total resistance

What is equal to the sum of all the resistances: Total R= R1 + R2 + R3,

flow of electrical charge

Current- Amps- A: The measured in Amperes (A) like water: tank= battery, pipe= wiring, faucet= switch, switch closed-> stops all electrons (100s and 1000s) from leaving SO open circuit= uncomplete path= no current= no flow || closed circuit= complete path= current= flow of electrons.

Electrons orbitals

: orbits in which electrons move around nucleus of an atom- valence electrons determines whether element is conductor or insulator- 1st= 8, 2nd= 8, 3rd= 18- 8 tends to be magic number in orbital- as orbits filled go further and further from nucleus EX: 29 [total electrons]- 2- 8- 18= 1 Valence Electron.
