Define the electric circuit ?

Question

Answer

An electrical circuit is a path in which electrons from a voltage or current source flow. The point where those electrons enter an electrical circuit is called the 'source' of electrons. The point where the electrons leave an electrical circuit is called the 'return' or 'earth ground'.

Answer

An electric circuit is a closed loop through which electric current can flow. A circuit must include a source of voltage and conductors such as wires to carry the current from the source of voltage and back again.

There are two types of electric circuit. - series and parallel.

In the scientific model for this kind of simple circuit, the moving charged particles, which are already present in the wires and in the light bulb filament, are electrons. ... When it is connected to a complete circuit, electrons move and energy is transferred from the battery to the components of the circuit.

The network of transistors, transformers, capacitors, connecting wires, and other electronic components within a single device such as a radio is also an electric circuit.

Answer

Electric Circuit:
An electric circuit is a closed pathway or loop that allows electricity to flow through it. It consists of various components, such as a power source, conductors, and loads, all interconnected by electrical wires. The flow of electricity in a circuit is driven by a voltage or electromotive force (EMF) provided by the power source.

Components of an Electric Circuit:
An electric circuit is made up of several key components, including:

1. Power Source: It is the device that provides the electrical energy to the circuit. The most common power sources are batteries and generators.

2. Conductors: These are materials that allow the flow of electric charges. Wires made of copper or aluminum are commonly used as conductors in circuits.

3. Loads: Loads are components in a circuit that convert electrical energy into other forms of energy, such as light, heat, or mechanical work. Examples of loads include light bulbs, motors, and heaters.

4. Switches: Switches are used to control the flow of electricity within a circuit. They can either complete or break the circuit, allowing or blocking the flow of electrons.

5. Resistors: Resistors are components that resist the flow of electric current. They are often used to control the amount of current flowing through a circuit.

6. Capacitors: Capacitors store electrical energy temporarily and release it when needed. They are commonly used in electronic devices to stabilize voltage levels.

7. Diodes: Diodes allow the flow of electric current in only one direction. They are commonly used in rectifier circuits to convert alternating current (AC) to direct current (DC).

How an Electric Circuit Works:
When a power source, such as a battery, is connected to a circuit, it creates an electric potential difference or voltage across the circuit. This voltage causes the flow of electric charges, or electrons, through the conductive pathway. The electrons move from the negative terminal of the power source, through the conductors and loads, and back to the positive terminal.

The flow of electrons is known as an electric current, which is measured in amperes (A). The current flows in a closed loop, continuously driven by the voltage provided by the power source. The conductors allow the electrons to move freely, while the loads convert the electrical energy into other useful forms.

Types of Electric Circuits:
There are two main types of electric circuits:

1. Series Circuit: In a series circuit, the components are connected in a single pathway, one after the other. The same current flows through all the components, and the total resistance is equal to the sum of individual resistances.

2. Parallel Circuit: In a parallel circuit, the components are connected in separate branches, allowing multiple pathways for the current to flow. The voltage across each component is the same, while the total current is divided among the branches based on their resistances.

Conclusion:
In summary, an electric circuit is a closed loop that allows the flow of electric current. It consists of various components, including a power source, conductors, and loads. The circuit operates based on the voltage provided by the power source, and the
