The voltage is the difference between two points in an electrical field and is measured in
volts (V)
...
The current is a flow of electrons and is measured in Amps (I)
...
Resistance is how much obstruction is given in the flow of electricity and is measured in
Ohms (Ω)
...
Another property that can increase/decrease resistance is the thickness of a wire,
the thicker the wire the less resistance as the electrons have more space to move
about and thinner the wire the higher the resistance as the electrons have less space
to move about
...
Longer wires generally have a higher resistance than shorter ones as the electron’s
energy will decrease the further they travel
...
