Direct current (DC) is the one directional or unidirectional flow electric charge. Electric current flows in two ways: either in an alternating current (AC) or in a direct current (DC). Let us assume that initially, the switch is turned off. Electrical circuits, AC and DC Electrical circuits are connected in series or in parallel. A DC circuit has current flowing in only one direction and is usually powered by a battery.

As an adjective, the term DC is used in reference to voltage whose polarity never reverses. The term DC means direct current. To explain the physics behind the different current readings across the circuit. An electrochemical cell is a prime example of DC power.
In alternating current, current keeps switching directions periodically – forward and backward.
The principle circuit elements are: When a switch is closed in a DC circuit, charges in the wire do NOT instantaneously start moving at the speed of light. While in the direct current it flows in a single direction steadily.
To understand how a potential difference (voltage) can cause an electric current flow through a conductor.
3. 2. To understand the relationship between voltage, current, and resistance in a DC circuit.
DC (direct current) is the unidirectional flow or movement of electric charge carriers (which are usually electron s). Each of them can be controlled individually with the help of a separate switch.In such type of circuit all the lamps are controlled by the single switch and they cannot be controlled individually.The most common application of this circuit is for decoration purpose where a number of low voltage lamps are connected in series.A simple DC circuit is shown in the figure below which contains a DC source (battery), a load lamp, a switch, connecting leads, and measuring instruments like ammeter and voltmeter.The load resistor is connected in series, parallel or series-parallel combination as per requirement.The DC electric circuit is mainly classified into three groups. DC Circuit Definition: The closed path in which the direct current flows is called the DC circuit. The current flows in only one direction and it is mostly used in low voltage applications. Direct Current (DC) electrical circuit Consider an electrical circuit consisting of a battery, on/off switch and a bulb. All the resistance is operated to the same voltage, therefore all of them are connected in parallel. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. In DC Circuit, the capacitor charges slowly, until the charging voltage of a capacitor is equal to the supply voltage. Also, in this condition the capacitor doesn’t allow the current to pass through it after it gets fully charged.
They are the series DC circuit, parallel DC circuit, and series and parallel DC circuit.The circuit which have DC source and one end of all the resistors is joined to a common point and other end are also joined to another common point so that current flows through them is called a DC parallel circuit. The resistor is the main component of the DC circuit. 1. If you take a continuous source of DC electricity, such as a battery, and connect conducting wires from the positive and negative poles of the battery to an electrical device such as a light bulb, you have formed an electric circuit.The battery, bulb and switch inside a flashlight form a DC circuitIn other words, the electricity flows in a loop from one end of the battery (or source of electricity) to the other end in a circuit.
Circuit components are shown as symbols. Turn off means a breakdown in the electrical current path.
