ELECTRICAL CIRCUITS

What is an electrical circuit?
Its a closed pathway trhough which electrons flow

Key words:

Voltage: Its the electrical charge of a battery or power supply. Volts (v)
Current: Its the flow of electrons in the circuit. Amperes (amps)I
Resistor: Its a component that opposes to the flow of electrons (R)

Ley de ohm
V: I x R
I: V/R
R: V/I
