Types of circuits

Fornula: image

Resistance: The opposition to the flow of elctric current.

Voltage: The difference in the charge between two points, which makes the electrons moves

Current: The intensity of the current or the amount of elctrons flowing through a conductor over a certain time.

Series circuits: All the components are connected one after the other. image

Parallel circuits: The load devices are connected on different branches of the wire. image

Series-parallel combination circuits: Contain devices connected in series and in parallel. image
