physics revision electricity

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