What type of material will you find all the way around the outside of an electric circuit to protect it?
insulation
What is emission?
a type of nebula
Which type of heat transfer is by direct contract?
The type of heat transfer by direct contact is called conduction. Heat is transferred through a solid material or between two objects in direct contact with each other. This occurs as the particles in the material or objects collide and transfer energy to each other.
What affects electrical resistance?
Primary Factors:For a simple system like an electrical wire, there are three major things which will affect the electric resistance.1. Resistance of wire conductor depends upon the material of which it is made.2. Resistance of wire conductor is directly proportional to its length.3. Resistance of a wire conductor is inversely proportional to its area of cross-section. (At least for low frequency voltage.)Additional:In general every material has a characteristic electrical conductivity (and resistivity) which determines how well it will conduct electricity. Metals have very high conductivities and insulators very low. The geometry of an object affects the resistance with the above-mentioned wire geometry being the most important example.In general the type of material and the geometry are the primary factors in determining the resistance of an object, but there are other effects worth mentioning.Temperature can change electrical properties of a material and there are some dramatic examples such as superconductors. Semiconductors can also have important temperature dependent properties. For most generic materials there is a rise in resistance with an increase in temperature but the effect is not usually large.More exotic phenomena also exist, such as the change in resistance due to a magnetic field or nonlinear conductors which do not have a fixed resistance but rather have a resistance that depends on voltage. Conductivity through a gas is a dramatic example of the latter.
Why does the resistance of a thermistor change when you change its temperature?
The resistance of a thermistor changes when its temperature changes due to the inherent properties of the thermistor material. In a negative temperature coefficient (NTC) thermistor, the resistance decreases as the temperature increases, whereas in a positive temperature coefficient (PTC) thermistor, the resistance increases as the temperature rises. This change in resistance is caused by the variation in the number of charge carriers (electrons or holes) and their mobility within the material as temperature changes.
What is bulk resistivity?
Bulk resistance is the ohmic resistance of the semiconductor material. The natural resistance of a "P" type or "N" type semiconductor material.
Heating coils made of which material in a furnace?
If you mean an electric furnace then normally it is nichrome. a heating element in a heat strip is made of what type of wire
How many watts does an electric heater use?
An electric heater is an electric appliance that convert electrical energy in to heat. Working principle of an electric heater as per "Joule heating theory" When electric current passes through a resistor that electric energy convert to heat (best and simple example is a spring type heating element). When Voltage applied both end of a wire/spring type Resistance wire, voltage flow and this voltage help that wire to heat up and convert in to heat. A Resistance wire quality, length & thickness depend how many time heat spread and resist with that heat. K.watt/ Watt = Applied voltage x Ampere. Many quality and types of electric heating elements are there depend upon purpose of use. Few best heating elements known as Kanthal wire, Nicrome wire, Ureka wire, Super Kanthal, Silicon Carbide heating elements etc.

What is a type of material that let's heat flow through it easily?
metal
How do mittens regulate heat?
The mittens are able to regulate heat because of the type of material that they are made up of.
