A simple model of a circuit?

Answer 1

An electric circuit is a closed loop that allows a flow of electrons to begin from a source of the electrons and return to the same source.

Some of the energy carried by the current from the source may or may not be released to perform useful work.

Because of the resistance of the materials in the circuit, some of the energy carried by the current is always lost as heat emitted from the circuit into the surrounding environment.

The flow of electrons around the closed loop is called an electric current.

The source of the electrons must be a chemical battery or a mechanical generator which produces a potential difference, also known as a voltage.

Answer 2

An electric circuit the closed path of electron flow from a current source. The point where the electrons first enter the circuit is known as the "source," while the point where they exit is known as the "return." The portion of the path between the source and the return is called the "load" of the electrical circuit. A simple electric circuit is one that only contains the minimum attributes required for the circuit to function.

A simple electric circuit requires only three characteristics in order to work properly. The circuit must have a source, a conductive path, and a resistor. The source, which emits the electrons, is usually an electrical outlet or a battery. The conductive path must be a medium that can transfer the electrons and is typically some kind of wire. The resistor is any object that can use electrons to perform its function, such as a speaker, light bulb, heating element, or electric motor.

Though this type of circuit is the simplest possible variety, it can be extremely useful. In fact, simple electric circuits are found in a variety of fixtures in any building or home. For example, simple electric circuits can be found in doorbells, flashlights, and many of the smaller kitchen appliances.

Simple electric circuits are considered one of the best functional examples of the typical behavior of electric current. The circuit's source raises the level of energy associated with the electrons. The electrons then move along the path and through the resistor. Once the electrons reach the resistor, they do work on it which causes them to lose energy. When the electrons return to the battery or other source, they have lost all of their energy. The drop in energy that occurs as a result of work done on the resistor is equal to the rise in energy obtained from the source.

A simple electric circuit is one of the most common and easily constructed circuits. These simple circuits can be found in many locations around the typical home and are often used to teach the behavior of electrical current. Since they are relatively simple to make, most middle school and high school students will see these circuits several times in Physics class. Without the simple electric circuit, a large number of everyday electrical appliances would not be able to function.

Answer 3

For many, electricity is a mystery. To understand a simple electric circuit that operates many useful appliances and devices, electricity must be understood. Electricity is the flow of electrons. Think of water flowing in a circular ditch with a pump or paddle wheel that keeps it flowing. The pump is what makes it flow. Electricity is the same way. The alternator, battery, or dynamo is what makes electrons flow.

Think of the water in the ditch moving because of the pump that moves it. Think of the water moving a wheel that drives an axle to do some useful work, such as a grinder. Now think of a simple electric circuit such as a lamp. In order for the light to glow, there must be a flow of electrons. This is done by plugging the lamp into the wall and turning or pushing the switch to make the bulb glow. With the switch turned on, the circuit is complete, or closed. With the switch turned off the circuit is incomplete, or open. The electrons stop flowing and the bulb doesn't glow.

Now think of the common flash light. The circuit consists of a load, which is the bulb, a switch, and the batteries. When the simple electric circuit is complete, the switch is turned on, or closed. The flow of electrons flows through the batteries, the conductors or wires, through the switch, and through the filament in the bulb. The bulb glows. When the switch is turned off, or open, the flow of electrons is stopped and the bulb stops glowing.

To get a better understanding of the simple electric circuit, build one. Get a six volt bulb. Get a common light switch. Get a six volt battery. Attach a wire to one terminal of the battery. Tape the same wire to the bottom of the bulb. Tape another wire to the part of the bulb that sits in the socket. Fasten the other end of that wire to the light switch. Fasten another wire to the other screw on the light switch. Attach the other end of that wire to the other terminal of the battery. When the switch is turned on, or closed, the bulb will burn. This is the simple electric circuit illustrated. Have fun!

Answer 4

A simple electrical circuit has one path for electrical current (electrons) to flow. A simple circuit has a power supply, switch/push button, and a load (light, bell, etc).
