Answers
the minimum requirements for causing flow of current are voltage source and a conductor.
Three things are required to generate an electric current: a supply of free-flowing electric charges (electrons), some sort of push to move the charges through the circuit, and a channel to convey the charges.
The electrical force that enables free electrons to flow from one atom to another is known as voltage. Electrical current, like water, requires a certain amount of force in order to travel through a conduit. The "electrical pressure" that causes current flow is measured in "volts."
•A voltage source and a conductor must be present in order to set a current flow.
•Current is defined as the rate of flow of charge.
•When voltage is applied across a conductor it creates potential difference which enables the electrons to move from high potential to low potential ,hence producing current.
