The amount of work done by an electric circuit is known as electrical energy. This energy is typically measured in joules and is a result of the movement of electric charge through a potential difference. The work done can be calculated using the formula ( W = V \times I \times t ), where ( W ) is the work (or energy), ( V ) is the voltage, ( I ) is the current, and ( t ) is the time for which the current flows.

What does the work in an electric circuit?
The work in an electric circuit is done by the flow of electric charge, typically achieved by the movement of electrons through a conductor. Work is done when a voltage is applied to the circuit, causing the electrons to move and transfer energy to the components in the circuit like light bulbs or motors.
What happens to an electric current when a circuit is closed?
When a circuit is closed, meaning there is a complete path for the electric current to flow, the current will flow from the positive terminal of the voltage source through the circuit components and back to the negative terminal. This flow of current allows electrical energy to be transferred and work to be done in the circuit.
How can the flow of electric current be started and stopped?
Electric current can be started by closing a circuit, allowing the flow of electrons. This can be done by pressing a switch to complete the circuit. To stop the flow of electric current, the circuit needs to be opened, typically by opening the switch, which interrupts the flow of electrons.
What do you mean bu electric potential?
Electric potential is a scalar quantity that represents the amount of electric potential energy per unit charge in a specific location in an electric field. It is a measure of the work done in moving a unit positive charge from infinity to that specific location without producing an acceleration. The unit for electric potential is volts (V).
Can current electricity be turned off?
Yes, current electricity can be turned off by interrupting the flow of electric current in a circuit. This can be done using switches, circuit breakers, or fuses, which disconnect the electrical supply. When the circuit is opened, the flow of electrons is halted, effectively turning off the electricity.
What is the amount of work done by an electric circuit?
The amount of work done by an electric circuit is equal to the product of the voltage applied to the circuit and the total charge that flows through it. Work done (W) = Voltage (V) x Charge (Q) = V x Q.

The work in an electric circuit is done by the flow of electric charge, typically achieved by the movement of electrons through a conductor. Work is done when a voltage is applied to the circuit, causing the electrons to move and transfer energy to the components in the circuit like light bulbs or motors.
What is the amount of electric potential energy per unit?
The amount of electric potential energy per unit charge is known as electric potential, measured in volts (V). It represents the work done to move a unit positive charge from a reference point to a specific point in an electric field.
Does electric dryer get damaged by short circuit in socket?
The fuse is there to disconnect the supply when there is a short circuit, before any damage is done.
What happens to an electric current when a circuit is closed?
When a circuit is closed, meaning there is a complete path for the electric current to flow, the current will flow from the positive terminal of the voltage source through the circuit components and back to the negative terminal. This flow of current allows electrical energy to be transferred and work to be done in the circuit.
Why does electricity give power?
Electricity doesn't give power. Power is simply the rate at which work is done in an electric circuit.
How can the flow of electric current be started and stopped?
Electric current can be started by closing a circuit, allowing the flow of electrons. This can be done by pressing a switch to complete the circuit. To stop the flow of electric current, the circuit needs to be opened, typically by opening the switch, which interrupts the flow of electrons.

Electric fences are not connected to the ground in the circuit?
A short answer:An electric fence is connected to the ground only when an animal or a human being touches it to complete a circuit from the fence to the ground.A longer answer:The wires of an electric fence are not connected directly to the ground because, if that was done, the fence would be shorted out and would not be able to do its job!This is how an electric fence is actually hooked-up: the electric fence is connected to one side of a specially designed high voltage source and the return side of that source is connected to the ground.Then, whenever the skin of any animal - or human - touches the wire whilst standing on the ground in bare feet, they get a high-voltage (10,000) DC electric pulse from the electric fence. The shocks are designed to be only enough to make them jump back from the fence, not to "electrocute" them so badly as to cause serious injury or death.
The amount of work done by heat engine equals the amount of what?
The amount of work done by a heat engine equals the difference between the heat input and the heat output of the engine. This is known as the heat engine's thermal efficiency.
Can current electricity be turned off?
Yes, current electricity can be turned off by interrupting the flow of electric current in a circuit. This can be done using switches, circuit breakers, or fuses, which disconnect the electrical supply. When the circuit is opened, the flow of electrons is halted, effectively turning off the electricity.
How do electric companies calculate electric energy being used?
Electric companies typically calculate electric energy usage by measuring the amount of electricity consumed in kilowatt-hours (kWh). This is done using electric meters that monitor the flow of electricity into a property over a given period of time. The total energy usage is then calculated based on the amount of power consumed and the duration of usage.
