A circuit is a complete path around which electricity can flow. It must include a source of electricity, such as a battery. Materials that allow electric current to pass through them easily, called conductors, can be used to link the positive and negative ends of a battery, creating a circuit.
What is electric circuit in short answer?
Electric circuit, path for transmitting electric current. An electric circuit includes a device that gives energy to the charged particles constituting the current, such as a battery or a generator; devices that use current, such as lamps, electric motors, or computers; and the connecting wires or transmission lines.
What is an electric circuit class?
A continuous and closed path of an electric current is called an electric circuit. An electric circuit consists of electric devices, a source of electricity and wires that are connected with the help of a switch.
What is an electric circuit for Class 7?
Answer: An electric circuit can be defined as a closed path through which electric current can flow. Various components such as battery, resistor, wire, key, bulb etc. can be connected in different ways to construct an electric circuit.
What is electric circuit with diagram?
A circuit diagram (also known as an electrical diagram, elementary diagram, or electronic schematic) is a simplified conventional graphical representation of an electrical circuit. … Arrangement of the components interconnections on the diagram does not correspond to their physical locations in the finished device.
What is an example of electric circuit?
An electric circuit is a connection of components that can conduct electric current. … Every circuit is designed to deliver power to one or more loads. For example, in a boombox the power goes to the speakers. Similarly, the power in a lamp goes to the light bulb.
What is the formula of electric circuit?
A simple circuit is one in which there is a single voltage source and a single resistance. One statement of Ohm’s law gives the relationship between current I, voltage V, and resistance R in a simple circuit to be I=VR I = V R . Resistance has units of ohms (Ω), related to volts and amperes by 1 Ω = 1 V/A.
What are the 4 parts of an electric circuit?
Every electric circuit, regardless of where it is or how large or small it is, has four basic parts: an energy source (AC or DC), a conductor (wire), an electrical load (device), and at least one controller (switch). Visualize what happens when you switch on a room light.
What are the three components of electric circuit?
Electric circuits
An electric circuit has three parts: An energy source – like a battery or mains power. An energy receiver – like a lightbulb. An energy pathway – like a wire.
What are the five parts of a basic electrical circuit?
The basic components of analog circuits are wires, resistors, capacitors, inductors, diodes, and transistors. Analog circuits are very commonly represented in schematic diagrams, in which wires are shown as lines, and each component has a unique symbol.
What is electric circuit and its types?
There are actually 5 main types of electrical circuits: Close circuit, open circuit, short circuit, series circuit, and parallel circuit. Each type of circuit is designed to create a conductive path of current or electricity.
What is the function of electric bulb?
A bulb converts electrical energy to light. When electric current flows through it, the bulb produces light.
