# What is meant by electric circuit?

continuous and closed path of electric current electric circuit is called. One electric circuit It consists of electrical equipment, power sources and wires which are connected with the help of a switch.

One electric circuit can be defined as a closed path through which electric current can flow. Various components like battery, resistor, wire, key, bulb etc.

electric circuit The flow or movement of electrons through it is called electric current. Current is measured in amperes. One ampere corresponds to about 6 billion electrons passing through a point in that circuit every second.

Electric circuit, a route for transmitting electric current. An electrical circuit consists of a device which Electric current Gives energy to the charged particles that make up a battery, such as a battery or generator; devices that use current, such as lamps, electric motors, or computers; and connecting wire or transmission line.

A circuit is a complete path around which electricity can flow. This should include a power source such as a battery. material that electric current which allows the current to pass easily through them, which are called conductors, can be used to connect the positive and negative ends of the battery, forming a circuit.

An electrical circuit is a network consisting of a closed-loop that gives a return path for current to flow. The flow of electric current must be able to pass from one terminal of the power source to the other. Electricity The source is the cause of the flow of current; It can be a voltage source or a current source.

## What are the types of electric circuits

electric circuit four There are types –

• open circuit – Open Circuit
• closed circuit – Closed Circuit
• short circuit – Short Circuit
• leakage circuit – Leakage Circuit

### what is open circuit

When the switch is turned off or due to any other reason, the path of the circuit is opened and the current does not flow in the circuit, this condition is called open circuit it is said. An electric circuit in which continuity is broken so that current cannot flow.

### what is a closed circuit

When the switch is turned on, the path of the circuit is completed and current starts flowing in the circuit. closed circuit it is said. A circuit without interruption, provides a continuous path through which a current can flow.

### short circuit Or what is called a short circuit?

A short circuit is an abnormal connection between two nodes of an electric circuit that are intended to be at different voltages. This results in an electric current limited only by the Thevenin equivalent resistance of the rest of the network which can cause circuit damage, overheating, fire or explosion?

### What is a leakage circuit called?

Leakage current flows in equipment when there is an unintentional electrical connection between ground and an active part or conductor. Leakage current is the current that travels through the protective ground conductor to ground. In the absence of a grounding connection, this is the current that can flow from the surface of any conductive part or non-conductive parts to ground if a conductive path is available (such as the human body). Leakage in devices is largely due to imperfections in insulators or materials that make up components such as semiconductors and capacitors.

## Important questions related to electricity-

### What is meant by electric circuit?

The continuous and closed path of an electric current is called an electric circuit.

### Write the definition of the unit of electric current.

The SI unit of electric current is the ampere (A). The rate of flow of electric charge is called electric current.
Hence, current = charge/time, the SI unit of charge is the coulomb (C). and the SI unit of time is the second (s).
Thus, unit of current =Cs=C s−1=Cs=C s-1
Therefore, the composition of 1 ampere electric current is the flow of one coulomb of charge per second.

### Calculate the number of electrons making up one coulomb of charge.

Charge on an electron =1.6×10(_19)=1.6×10(_19) coulomb

or, =1.6×10(_19)=1.6×10(_19) coulomb charge = 1 electron
So 1 C charge =11.6×10(−19)=11.6×10(-19) electron
=10191.6=10191.6 electron

=10×10181.6=10×10181.6 electrons
=6.25×1018=6.25×1018 electrons

### Name the device which helps in maintaining the potential difference across the ends of a conductor.

battery or cell,
ExplanationA battery or device is a device that helps to maintain the potential difference across the ends of a conductor.
