Chapter One Electricity (Section 1.1 Materials can become electrically…

- - - - Static charges are caused by the movement of electrons
        
        Materials in contact are opposite eachother
        
        Electrons move from one atom to another
        
        Induction is the build up of a charge without direct contact this produces a temporary static charge
        
        Charge polarization it means that there is a stronger negative pull
- - - - Materials effecting electric charge are conductors and insulator
        
        Resistance are a property of a material that determines how easily a charge can move through it
    - - Electric potential is measured in units called volts
        
        OHMS measures an electrical resistance
- - - - Electric current is a form of electricity, the size and pressure effect the flow.
        
        Current = Voltage/resistance I=V/R
        
        Voltmeter ohmeter and amneter are instrucments to measure amps
        
        Primary cells are not rechargeable chemical reactions keep occurring until its out.
        
        storage cells can recharge and also use chemical reactions
        
        Electric cell produces electric current using chemical or physical properties of different materials, one way electric current can be used is two strips made of different materials
        
        Primary Cells are both wet cells and dry cells usually
        
        Storage cells produce current through chemical reactions that can be stored
