Related terms

Current:

Current refers to the flow of electric charge (electrons) in an electrical circuit.

Resistance:

Resistance is the opposition offered by materials to the flow of electric current. It determines how difficult it is for current to pass through.

Series Circuit: In series circuits, components are connected one after another along the same path so that there's only one path for current to flow.
