What are the conductors and insulators in a simple circuit?
All materials are conductors and insulators to some extent. Materials called "conductors" have very high conductivity, and materials called "insulators" have very low conductivity. Wires are the conductors in a circuit. Wires are usually wrapped with insulators so that accidental contact between wires does not cause a "short" and prevent the circuit from working as designed. Also, air is a good insulator that is usually implicitly present between the components of the circuit. These insulators are not drawn on a circuit diagram. They are represented by the absence of a connection drawn on the diagram. In a sense, they are not part of the "circuit", because they are not part the path taken by the vast majority of electrons. Resistors are a kind of electrical component that is between a conductor and an insulator. They can conduct electricity to some degree, but less than a wire. Capacitors contain an insulator called a "dielectric". This material does not allow electrons to pass. However, current can pass through a capacitor. Excess electrons can accumulate on one side of the capacitor, while electrons are drained from the other side. No electrons actually pass through the capacitor, but they seem to because the same number enter on one side as leave on the other.
What are three reason why a simple circuit may not work?
The circuit may not be complete. The power source may not be sufficient. The polarity of the battery is messed up.
Who invented the series circuit?
The series circuit was first invented by Danny niez in 1995. Mr. NIez is Mr. LAX!!!!
What are two things required to make electric current flow in a circuit?
you need an electrical supply and a load. nice and simple.
What is an electric curcuit?
An electrical circuit is a collection of electrical devices which are connected in a loop for electricity to flow through from high potential to low potential. A battery connect to light bulb is one simple form of so-called circuit :)

What materials are conductors in a torch?
The conducting path of a torch is a simple circuit: Battery to switch, switch to bulb, bulb back to battery. Provided the switch is on, and there are no breaks in the circuit wiring (and the bulb is good), the torch should work.
Is a poor conductor of heat?
Most metals are good conductors of heat, but lead and stainless steel are exceptions. Air is a poor conductor of heat as are fibrous or layered materials. Cloth made from cotton or asbestos or sisal would be poor conductors. Mica would be an example of a layered material that is poor. In most thermal insulators, all you are buying is still air, because still air is (almost) the poorest conductor of heat among the simple materials. Hence the construction of most thermal insulators.
What parts are necessary for a simple complete circuit?
-- power supply -- power-dissipating component -- connecting conductors
Example of insulators?
There are plenty of examples of insulators. Insulators can be as simple as air or as complex as mixed fiberglass.
What causes overheating and fires associated with overloaded circuites?
When a circuit is overloaded, the wires gain a lot of heat over a short time. The heating can cause sparks and shorting and these can in turn set up fires if they come into contact with combustible materials.
Why some materials are insulators?
because thats just the way it is, simple as that.
What is a poor conductor of heat?
A poor conductor of heat is usually refereed as an insulator, the reason being is because Metal conceives over thousands of particles, these particles then vibrate between one another causing it to spread dramatically, this process speeds up the heating, enabling it to be hotter then usual. However, None-Metals are called "Insulators" Insulator meaning the particles are either too close to each other or spread out further, a wooden spoon can be described to be a insulator because it doesn't conduct with heat.
What is a circuit What can you use it for?
In electronics, a circuit is a complete circular path that electricity flows through. A simple circuit consists of a current source, conductors and a load. The term circuit can be used in a general sense to refer to any fixed path that electricity, data or a signal can travel through.
Why do most thermometers use liquids?
Prior to semi-conductors, liquid was the practial way. Simple materials and construction. Accurate and reliable. Physics dont lie.
Is it necessary to measure the conductivity of a material?
In many cases, yes, it is necessary to measure the conductivity of a material. We need to know how well materials conduct electricity, particularly if these materials are used in the construction of anything electrical or electronic. We need to know what we can use around electrical circuits that won't conduct well, and we need to find things to make up that circuit that are good conductors. Simple, easy to understand.
A simple circuit?
A simple circuit is a basic, simple and complete path through which electricity can flow.
