Ohms law
-
Ohms laws experiment conclusion- As the potential difference increases, so does the current
-
-
Charge flow (coulumbs, C) = current (Amps, A) x time (seconds, s)
Q = I x t
-
-
-Potential difference makes current flow through resistors
-High resistor, more energy needed
-Current takes path with less/ low resistance
To not get shocked:
Difference in voltage causes electricity to pass from one to another.
Humans are at 0V. So if we were to touch live wire, we would get an electric shock because of large current.
raise potential difference to be the same as electricity- no current
Plugs
3 types of wires:
-Neutral (blue)- completes the circuit and carries current away. it has 0V
-Earth wire (green + yellow)- Stops appliance casing from becoming live. Provides an alternative pathway, takes the current to flow away, rather than to us. Is normaly at 0V
-If live wire came loose and touched the casing, electric shock.
-Live (brown)- Provides the alternating potential difference from the main supply. Normally at 230V
types of energy stores:

-gravitational potential
-thermal
-magnetic
