Electrical Circuits
Electrons
Found in outershells
Smaller then protons and neutrons
Negative charge (-)
Number of electrons is equal to the number of protons
Currents in metal
Electrons in metals are removed easily
Battery in a wire pushes electrons around the circuit
Electrons move from negative terminal to a positive terminal
Current is flow of electrons around a circuit
Protons, Electrons and Neutrons
Protons
Charge of +1
Mass of 1
Found in the protons
Electron
Charge of -1
Mass of 1/1835
Found in the outershells
Neutron
Mass of 1
Charge of 0
Found in the nucleus
Circuits
Series
Electrons only have 1 route to take. lamps cannot be switched off individually
Parallel
Electrons have more then 1 route to take. Lamps can be switched off individually
