Question

name some source of direct current ​

Answer 1

Explanation:

=>Direct current is produced by sources such as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type.

Direct current may flow in a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams.

Answer 2

$\huge\sf{Overview}$

$\bold{Different~Types~of~Currents}$

An electrical circuit is an interconnection of electrical elements that has a closed loop giving a return path for the current.

$\sf{Key~ Points}$

• Direct current ( DC ) is the unidirectional flow of electric charge. Direct current is produced by sources such as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type.
• A direct current circuit is an electrical circuit that consists of constant voltage sources, constant current sources, and resistors. It is common to refer to a circuit that is powered by a DC voltage source as a DC circuit even though what is meant is that the circuit is DC powered.
• A number of electrical laws apply to all electrical networks: Ohm ‘s law, Kirchhoff’s current and voltage laws, Norton’s theorem, and Thévenin’s theorem. With these, it is possible to calculate the electric potential and current at each point in the circuit.

$\sf{Key ~Terms}$

• current-voltage characteristic: A current–voltage characteristic or I–V curve (current–voltage curve) is a relationship between the electric current through a circuit, device, or material, and the corresponding voltage, or potential difference across it.
• electrical circuit: An interconnection of electrical elements such as resistors, inductors, capacitors, transmission lines, voltage sources, current sources and switches that has a closed loop giving a return path for the current.
• direct current: An electric current in which the electrons flow in one direction, but may vary with time.
