Ultimately this is a special case of the Second Law of Thermodynamics.In the case of an electric circuit, consider Ohm's Law. Without a voltage, you will have no current.

Also, if a current flows, keeping up the voltage requires power.

What is the third part of an electric circuit besides the wires and the load?

The third part of an electric circuit is the power source, which provides the electrical energy needed to drive the current through the circuit and power the load. This can be a battery, generator, or power supply depending on the application.


Is it necessary to have cell in electric circuit?

A cell basically works as a producer of a potential difference in the circuit which is necessary for the electrons to travel in a region. Therefore using this principle we can understand that almost anything that can produce a PD can be used in an electric circuit. The best example would be of emf through EM induction of the Faraday's experiment


What are the two things needed to make current flow in electricity?

A flow of electrons is needed to have a current. And there (usually) must be a complete circuit. And you need a voltage to make the current move around your circuit. All tied up in Ohms Law - which I'll leave to you.


Is NOT needed to form an electric circuit?

A complete electric circuit does not require a switch. While a switch is useful for controlling the flow of electricity, the basic components needed to form a circuit include a power source (like a battery), conductive pathway (like wires), and a load (like a light bulb) that uses the electricity. Without these elements, electricity cannot flow and complete the circuit.


You need a cell in the circuit because?

Assuming you are talking about electrical circuits: "Cell" is the name given for a battery. Without a cell in the circuit, there is no supply of electricity. Therefore there is no electric circuit.

Why is an energy source needed in order to have a working electric ciruit?

An energy source is needed to provide electrical energy to the circuit components such as resistors, capacitors, and bulbs. Without an energy source, there would be no electrical current flowing through the circuit, and no power for the devices to operate.


What is electric potential energy in a circuit?

Electric potential energy in a circuit refers to the energy stored due to the position of electric charges within an electric field. It is related to the voltage (or electric potential) across components in the circuit, indicating how much work is needed to move a charge from one point to another. This energy is converted to other forms, such as kinetic energy or thermal energy, as charges flow through the circuit, powering devices and performing work. The electric potential energy is crucial for understanding how circuits operate and the energy transformations that occur within them.


What is the source of energy in the circuit?

battery, generator, alternator, etc.


What is the source of voltage in an electrical circuit?

The source of voltage in an electrical circuit is typically a power source, such as a battery or a generator, that provides the energy needed to push electric charges through the circuit.

What is the object called that supplies energy to move current through a circuit?

The object is called a power source, such as a battery or a generator, which provides the energy needed to move current through a circuit.


What supplies energy to move elecricity through a circuit?

In a circuit, the energy needed to move electricity is provided by a power source such as a battery or a generator. This power source creates a voltage difference between the circuit's components, which pushes the electric charges to flow through the circuit.


What is the role of the battery in a circuit diagram?

The battery in a circuit diagram provides the electrical energy needed to power the components in the circuit. It acts as a source of voltage, creating a potential difference that drives the flow of electric current through the circuit.


What is needed to have and electric current?

To have an electric current, you need a closed circuit that allows the flow of charged particles, such as electrons. This circuit typically includes a source of electrical energy, like a battery or generator, conductive materials (wires), and a load (such as a light bulb or motor) that uses the electrical energy.


Why is an energy source needed in order to have a working circuit?

The "why" is a bit hard to answer, but this is just part of a more general situation: you need an energy source to make ANYTHING work. The real reason for all this is the so-called "Second Law of Thermodynamics".Specifically in the case of an electrical circuit, a current will flow as a result of a voltage. The details are expressed in Ohm's Law.


What is the potential difference between two points in an electric circuit?

The potential difference between two points in an electric circuit is the measure of how much energy is needed to move a charge from one point to the other. It is also known as voltage and is measured in volts.
