How are electric circuits classified?
Electric circuits are classified in several ways. A direct-currentcircuit carries current that flows only in one direction. An alternating-currentcircuit carries current that pulsates back and forth many times each second, as in most household circuits. (For a more-detailed discussion of direct- and alternating-current circuits, seeelectricity: Direct electric currentand electricity: Alternating electric currents.) A series circuitcomprisesa path along which the whole current flows through each component. A parallel circuitcomprises branches so that the current divides and only part of it flows through any branch. The voltage, or potential difference, across each branch of a parallel circuit is the same, but the currents may vary. In a home electrical circuit, for instance, the same voltage is applied across each light or appliance, but each of these loads draws a different amount of current, according to its power requirements. A number of similar batteries connected in parallel provides greater current than a single battery, but the voltage is the same as for a single battery. See alsointegrated circuit; tuned circuit.

What is a circuit?
REVIEW: A circuit is an unbroken loop of conductive material that allows charge carriers to flow through continuously without beginning or end. If a circuit is “broken,” that means its conductive elements no longer form a complete path, and continuous charge flow cannot occur in it.
What Does It Mean When a Circuit Is Broken?
Continuity is just as important in a circuit as it is in a straight piece of wire. Just as in the example with the straight piece of wire between the Source and Destination, any break in this circuit will prevent charge from flowing through it:
Why is the location of a break in a circuit irrelevant?
The location of a break in a circuit is irrelevant to its inability to sustain continuous charge flow. Any break, anywhere in a circuit prevents the flow of charge carriers throughout the circuit.
What happens if a circuit is discontinuous?
Any discontinuity in the circuit will prevent charge flow throughout the entire circuit. Unless there is a continuous, unbroken loop of conductive material for charge carriers to flow through, a sustained flow simply cannot be maintained.

What is an Electric Circuit?
An electric circuit is a closed path in which an electric current can flow. A simple electric circuit comprises a source, a bulb or any other load and connecting wires. If terminals of a bulb are connected to the terminals of the source of electric current with the help of connecting wires, then a potential difference is set across its terminals. This causes the current to flow in the electric circuit, and the bulb glows. An electric circuit is said to be complete if all its parts are connected with wires made of conductors. If there is an insulator in the path of the circuit, it becomes incomplete.

Electricity is nothing but the flow of charge or current in an electric circuit. What causes the flow of current? The answer to this question is the potential difference across the terminals of an electrical device causes the current to flow through it. We can create this potential difference by connecting the electrical device with a source of energy like a cell. This simple arrangement of electrical components is called an electric circuit.

How does electricity come to the house?
Electricity is produced at electric power stations and transferred to our homes via transmission lines. This electricity reaches the electric boards that are fixed in our homes through the main power supply. There are three main wires via which the mains supply the electricity in our homes. One of these wires is called a live wire (or positive). The live wire has a red insulation cover, and the other wire is called neutral wire (or negative). This wire has a black insulation cover over it. A potential difference of 220 V is maintained between these two wires. These wires pass into an electric meter through the main fuse, which protects appliances from overloading. Through the main switch, they are connected to the line wires, which supply electricity to separate circuits within the house. We are usually provided with two different circuits, one of 15 A current rating, which is used for high power rating devices, and the other of 5 A current which is used for low power rating devices. The earth wire, which is covered with green insulation, is used to protect us from electric shock in case of any current leakage. It is connected to the ground, and it provides a low resistance path for the current.
