Power consumed by a resistance is I2R
Alloys can add heat resistance to a metal
because by definition heat capacity is how much heat the substance needs to change its temperature by 1 degree. It "stores" heat and delivers it back slowly. It has nothing to do with heat resistance which is how much heat it allows through it.
The amount of heat generated by 600 volts depends on the current flowing through the circuit and the resistance of the materials involved, as described by Joule's law (Q = I²R, where Q is heat, I is current, and R is resistance). Without knowing the current or the resistance, it's impossible to determine the exact amount of heat produced. In general, higher voltage can lead to more heat if current and resistance are also significant.
The resistance of a filament wire affects the amount of current passing through it and the amount of heat produced. Higher resistance leads to higher heat generation and light emission, resulting in brighter light. However, too much resistance can cause the filament to overheat and fail prematurely.
Not really, if you're referring to heat transfer, then the heat will use the path of least resistance. So the heat doesn't rely on the path as much as it does on the material that the heat must travel through.
You lose a lot of efficiency, since resistance heaters make heat off being inefficient.
When current flows through a material with resistance, electrical energy is converted into heat energy due to the collisions between electrons and atoms in the material. This increased kinetic energy in the material causes the temperature to rise and heat to be produced as a result of resistance.
a short or too much resistance thus heat
There are many ways how electricity can create heat. For example, passing a current through a wire of high resistance (i.e. a resistor) will generate heat, though not much.
Heat insulation is defined as the resistance to the flow of heat offered by a material when it is subject to a change in temperature. Objects that put up a lot of resistance to heat flow don't conduct heat well, and are called insulators. Some examples of insulators are wood, rubber and glass. Things that do conduct heat well don't offer much resistance to heat flow. Many metals fall into this category, such as aluminum, copper, and gold. See the link below for more information on heat conduction.
Yes, resistance in a conductor causes energy losses due to heat. Metals such as Gold and Platinum have very low resistance but they are very expensive so Copper and Aluminium are used instead which are much more affordable but have higher resistance.
The heat generated by an electric current is in watts, Current x volts. So current alone is not enough to define it. By Ohms Law, Volts = Current x Resistance, so another way of expressing watts is (Current squared) x Resistance. If you know the current andthe resistance you can get the wattage, which will give you the heat generated.
