Answer: 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 electric circuit and its unit?

An electric circuit is a path in which electrons from a voltage or current source flow. It’s SI unit is ampere(A) Niccherip5 and 5 more users found this answer helpful.

## What means electric circuit?

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 in short?

A circuit is a closed path that consists of circuit components in which electrons from a voltage or current source can flow. … The point where 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”.

## What is electric circuit for class 10th?

An electrical circuit is a network consisting of a closed-loop that gives a return path to the current flowing. The current flowing should be able to go from one terminal of the power source to the other.

## What is current unit?

The SI unit of current is ampere which measures the flow of electric charge across a surface at the rate of one coulomb per second. Since the charge is measured in coulombs and time in seconds, so the unit is coulomb/Sec (C/s) or amp.

## How is electricity measured in units?

A unit of energy equal to one kW applied for one hour; running a one kW equipment for one hour would dissipate one kWh of electrical energy as heat. The kilowatt-hour (symbolized kWh) is a unit of energy equivalent to one kilowatt (1 kW) of power expended for one hour (1 h) of time. 1 kWh = One thousand watt hours.

## What does an electric circuit mean define the unit of current calculate the number of electrons constituting one coulomb of charge?

Question 3: Calculate the number of electrons constituting one coulomb of charge. Answer: One electron possesses a charge of 1.6 × 10^{–}^{19} C, i.e., 1.6 × 10^{–}^{19} C of charge is contained in 1 electron. ∴ 1 C of charge is contained in 1 / 1.6×10^{–}^{19}= 6.25×10^{18}=6×10^{18} electrons.

## What is volt meter?

voltmeter, instrument that measures voltages of either direct or alternating electric current on a scale usually graduated in volts, millivolts (0.001 volt), or kilovolts (1,000 volts). Many voltmeters are digital, giving readings as numerical displays.

## What is an electric circuit class 7?

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 an electric circuit class 6?

Answer: The electric circuit is an arrangement that provides a pathway for the flow of electric current. It is a device comprising of switches, bulbs, wires and an electric cell.
