Question

What are the main components of an electric circuit and their uses?

Answer 1

Answer:

• An energy source (AC or DC).
• A conductor (wire),
• An electrical load (device).
• At least one controller (switch).

Explanation:

Alternating current:

• Alternating current tends to be used for power distribution.
• It has the advantage that it can easily be converted to other voltages using a simple transformer - transformers do not work with direct current.
• If power is distributed at a high voltage then the losses are much lower.
• Alternating current is important because it's voltage can be stepped up and down as required, thereby reducing power loss during transmission.
• Example: The most basic example of an alternating current is generated in a wire loop spinning in a magnetic field.

Direct current:

• The biggest advantage of DC electricity is that it is easier to store than AC electricity, especially on a small scale.
• Storing electricity when it is made, for use later when it is needed, is a critical concept for a hybrid independent power plant.
• Direct current is used in any electronic device with a battery for a power source.
• It is also used to charge batteries, so rechargeable devices like laptops and cell phones come with an AC adapter that converts alternating current to direct current.
• Example: The best real-life example of direct current is a battery. Batteries have positive (+) and negative (-) terminals. If you take a wire and connect the positive and negative terminals on a battery, the electrons in the wires will begin to flow to produce a current.

Conductor:

• Most importantly a conductor serves as a messenger for the composer.
• Conductors and insulators are both important in the field of electronics. Electrical conductors allow electric current to flow easily because of the make up of their atoms.
• In a conductor, the outer electrons of the atom are loosely bound and can freely move through the material when an electric charge is applied.

Device:

• A GFCI helps to prevent electric shock from faults in electrical devices used in homes.
• An AFCI device is a circuit breaker that protects against high power discharges of electricity when it detects an electric arc within its protected circuit.

Switch:

The purpose of a switch in a series circuit is to make it easy to open or close the electrical circuit, turning the flow of electricity on or off.

The purpose of the wires in a series circuit is to allow the electricity to flow from one device to the next.

Wire is used to carry the flow of electrons.

A switch in an electronic device is used to interrupt the flow of electricity or electric current.

Electrical switches are binary devices, they can be either completely off or completely on.

In simple English, a switch is an electronic device which is used to break or make the electronic circuit.
