physics revision electricity
- current
- current is measured by an amiter
- if the ammeter is first on a parallel circuit the parallel circuits power will be exactly half
- the curren will be the same when it is not the first thing drawing power from a curcit
- the derection of the current is always goeing clockwise
- current is the flow of electrical energy in a circuit
- current is measured by an amiter
- voltage
- voltage can also be called potential diferance
- voltage acts as a force to push electricity through wirers to where they need to be
- voltage is measured in volts with a voltmeter
- voltmeters are always put in parallel
- voltage can also be called potential diferance
- curcits
- a battery has 2 cells in it
- all bulbs in a parallel curcit will have the same amount of power
- a parallel circuit can go down levles
- a simple circuit is just one line going round until it meets the cell
- a battery has 2 cells in it
- curcits
