Electricity Circuts

                     Electricity Circuts : Individual, Series, Parallel and Series - Parallel



Voltage: The force that moves the electrons in a circuit.
Ampere (Amps): Is the measure of current ,the higher the current in a circuit the more reading you will get.
Ohms: Is the unit of resistance. This slows down  the flow of electrons.
Wattage: The measure of power that is being used.
Voltage drop: To show us how much voltage is being used up by each component in a circuit.
Available Voltage: This shows us how much voltage is available to work                                 
Individual Circuts
Individual circuits are a simple circuit, It had one light going, Only one path for the electricity to flow through.  The power supply was set to 12.74v.We learnt how to use a multimeter to read the available voltage voltage drop ,Amps but to measure amps the circuit needs to be broken at a point where the multimeter can be attached to the circuit so the current flows through it.To work out resistance the circuit needed to be turned

Series CircuitIn a seires curcuit electricity flows one way through all the components.The components use the same amount of volts and if one bulb stops all of them will stop working. There are less amps in a series circuit


Paralellel Circuits
In a parallel circuit each component has there own power supply and earth , therefore if one stops working the rest will keep going they all get the same amount of volts and in series there is less voltage because they share it
