Electric cuantities
Electic current is the charge, or number of electrons, that flows through a conductor per second
the resistance of the component is the quotient of the potential difference across it over the current flowing through it .
Voltage or tension is the energy that a battery or generator can provide for each electron. It is measured in volts (V).
