What is a basic electrical circuit?

An electric circuit is a path in which electrons from a voltage or current source flow. The point where those 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".
A.

What is an example of a circuit?

An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow.
  • What are the main components of a circuit?

    These are the most common components:
    • Resistors.
    • Capacitors.
    • LEDs.
    • Transistors.
    • Inductors.
    • Integrated Circuits.
  • What is a circuit in science?

    A closed path through which an electric current flows or may flow. ♦ Circuits in which a power source is connected to two or more components (such as light bulbs, or logic gates in a computer circuit), one after the other, are called series circuits.
  • What is a series current?

    A series circuit is a closed circuit in which the current follows one path, as opposed to a parallel circuit where the circuit is divided into two or more paths. In a series circuit, the current through each load is the same and the total voltage across the circuit is the sum of the voltages across each load.
B.

What are the four basic components of a circuit?

The Basic Parts of an Electric 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 three main parts of a circuit?

    The 3 main parts of an electric circuit and their functions are: Power source - Either electrical or battery, provides the power to the load. Load - The device using the electricity such as a computer, light bulb, power saw, etc.
  • What does current do in a parallel circuit?

    A parallel circuit has two or more paths for current to flow through. Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source.
  • How does current work?

    The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
