ELECTRIC CIRCUIT

ELECTRIC CIRCUIT: 

ELECTRIC CIRCUIT I- ELECTRIC CIRCUIT II- ELECTRIC PARTICLE III- Consolidation

ELECTRIC CIRCUIT: 

ELECTRIC CIRCUIT I- ELECTRIC CIRCUIT 1- Simple circuit Have you ever seen electric circuit ? 2- Conventional current According to the circuit bellow, how is the direction of the conventional current? 3- Conductor and Insulator

Conductor and Insulator: 

Conductor and Insulator Conductor Insulator

Conductor: 

Conductor The thing that conducts heat or electricity. Ex.: Solution of Acid, Base, Salt, Metal, Graphite… see more Please give some example of conductor

Conductor: 

Conductor

Conductor: 

Conductor Answer YES! Metal

Insulator: 

Insulator The thing that can not conduct heat or electricity. Ex.: Dry wood, rubber, gas, pure water... See more Student give some example of insulator.

Insulator: 

Insulator Pure Water Dry Wood

Insulator: 

Insulator Answer NO!

ELECTRIC CIRCUIT: 

ELECTRIC CIRCUIT II- ELECTRIC PARTICLE Positive charge Negative charge

Simple circuit: 

Simple circuit The set of battery, wire, lamp, switch, electric receiver is called electric circuit. Simple circuit

Simple circuit: 

Simple circuit some examples of electric circuit on Crocodile Physics. Electric Circuits Circuit01 Pictures02 Pictures03 Pictures04

Simple circuit: 

Simple circuit If we change the place of Ammeter, the current keep the same. See more

Simple circuit: 

Simple circuit If we change the terminal of the battery the direction of the current is changed. See more

Conventional current: 

Conventional current The direction of the conventional current is from positive terminal to negative terminal of generator. Show

Electric Particle: 

Electric Particle - The positive ion is called Cation: Na+, Cu+, Ag+…

Electric Particle: 

Electric Particle - The Negative ion is called Anion: cl-,OH-, SO4-, NO3- ...

Electric Particle: 

Na Na+ Electric Particle Cl Cl-

Electric Particle: 

Electric Particle

Electric Particle: 

Electric Particle The smallest electric particle is electron. The charge of electron: Mass of electron: Mass of Proton : Me x1836

Electric Particle: 

Electric Particle The Positive charge moves the same direction of conventional current. (click here) * The Negative charge moves opposite of conventional current. (click here)

Negative charge: 

Negative charge

Consolidation: 

Consolidation Students work in group by using Physic crocodile soft ware to form the simple electric circuit and present in the class. Go to physic crocodile
