- P3 : ELECTRIC CIRCUITS!
- STATIC ELECTRICITY
- bui;d up of static is casued by the transferring of electrons.
- similiar charges repel each other. opposite charges attract to each other.
- all electric charges have an electric field.
- an electric field is the space surrounding any electric current where the effects are felt.
- BASIC CIRCUITS
- total charge through the circuit depends on the current and time.
- circuit symbols you should know!
- motor
- amp/volt meter
- lamp (filament)
- resister
- open/closed switch
- battery
- fuse
- cell
- current can only flow round a closed system.
- FORMULAS!
- power = potential difference x current
- power = energy / time
- power = current (2) x resistance
- energy transferred = charge x potential difference

- potential difference = work done / charge
- PARALLEL CIRCUIT

- potential difference = current x resistance
- charge = current x time
- ELECTRO-MAGNETISM!
- a solenoid is a coil of wire
- magnets can be permanent or induced
- a current carrying solenoid in a magnetic field experiences force
- electromagnetic induction : the induction of a potential difference across a conductor which is experiencing a change in the magnetic field.
- discovering electromagnetic induction changes out lives forever.
- you can use an oscilloscope to see the generated P.D.
- induced current opposes the change that made it
- STATIC ELECTRICITY
