What is necessary to have continuous electric current in a circuit?

Electrical energy is energy produced by the movement of certain particles. … Now you know that electric current flows through a path called a circuit. You also know that a continuous electric current needs an energy source such as a battery.

What makes the continuous flow of electric current?

A constant potential difference can cause a continuous flow of electric current in a circuit. … The flow of electrons due to the push caused by a constant potential difference across C from B to A causes a flow of current from A to B in the opposite direction of the flow of electrons.

What is required to make an electric current flow in a circuit?

To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. … The flow of electricity can be likened to a flow of water through a pipe.

IT\'S FUNNING:  Which is the portable source of electric current?

What are the 4 requirements for an electrical 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).

What are the 3 requirements of a circuit?

Every circuit is comprised of three major components:

  • a conductive “path,” such as wire, or printed etches on a circuit board;
  • a “source” of electrical power, such as a battery or household wall outlet, and,
  • a “load” that needs electrical power to operate, such as a lamp.

What is needed to maintain a continuous flow of charge?

-To attain a sustained flow of charge in a conductor, some arrangement must be provided in water pressures- is maintained with the use of a pump. … -Electromagnetic induction at the generator terminals provide the electric pressure to move electrons through the circuit.

How can a circuit achieve a continuous flow of electrons?

How can a circuit achieve a continuous flow of electrons? For a continuous flow of electrons, there must be a complete circuit with no gaps. What happens to current in other lamps if one lamp in a series circuit burns out?

What is the minimum requirement to cause the flow of current?

the minimum requirements for causing flow of current are voltage source and a conductor. Three things are required to generate an electric current: a supply of free-flowing electric charges (electrons), some sort of push to move the charges through the circuit, and a channel to convey the charges.

Which of these is required to make a circuit?

Minimum components needed for an electrical circuit are a power supply, a load suited to the power supply, and wiring as a conductor. A switch controls current flow into a circuit.

IT\'S FUNNING:  Quick Answer: How do you recover from a nuclear plant emergency?

What is required for an electric charge to flow through a wire quizlet?

A difference in electrical potential is needed for charge to flow. The flow of charge persists as long as there is potential difference ; without a potential difference, or once both ends reach an equilibrium, flow ceases. … A continuous potential difference, often provided by a battery, is needed for charge to flow.

What are the 5 requirements for a complete electrical circuit?


  • Power Source is needed to supply the flow of electrons (electricity).
  • Protection Device prevents damage to the circuit in the event of a short.
  • Load Device converts the electricity into work.
  • Control Device allows the user control to turn the circuit on or off.

What are the 2 requirements of a circuit?

There must be an energy source (battery) capable of doing work on charge to move it from a low energy location to a high energy location. This establishes a potential between the two ends of an electric circuit. 2. There must be a closed conducting loop that connects from the high potential to the low potential.

What are the five elements needed for a practical circuit?

What are the five elements needed for a practical circuit? load, source, circuit control device/switch, conductor, circuit protection device/fuse.

What does an electric circuit consists of?

A simple electric circuit can consist of a battery (or other energy source), a light bulb (or other device that uses energy), and conducting wires that connect the two terminals of the battery to the two ends of the light bulb.
