What is the controlling resistance that determines the amount of heat flow through a composite wall?

The thermal resistance of the material with the highest resistance in the composite wall determines the amount of heat flow. Heat flow is restricted by the material with the highest resistance, which is often the material with the lowest thermal conductivity in the composite wall.


What changes electrical energy into thermal energy?

Electrical energy is converted into thermal energy through the process of resistance heating. This occurs when an electric current flows through a material with resistance, such as a heating element in a toaster or an electric stove. The resistance causes the material to heat up and emit thermal energy in the form of heat.


What are the thermal parameters?

Thermal parameters are characteristics that describe how heat is transferred in a material or system. These parameters include thermal conductivity, heat capacity, thermal diffusivity, and thermal resistance. They are important in determining how a material or system responds to changes in temperature.


What is the tendency for a material to oppose the electron flow and change electrical energy in to thermal energy and light?

The tendency for a material to oppose the flow of electrons and convert electrical energy into thermal energy and light is known as resistance. This property is determined by the material's resistivity and is quantified in ohms (Ω). The higher the resistance of a material, the more it will convert electrical energy into heat and light.


Which material is best of insulation?

The best material for insulation depends on the specific application and requirements. Commonly used materials include fiberglass, foam, cellulose, and mineral wool. Factors to consider when choosing insulation material include thermal resistance, moisture resistance, cost, and environmental impact.

How the heat losses through insulation can be calculated?

Heat losses through insulation can be calculated using the formula Q = (T1 - T2) / R, where Q is the heat loss, T1 and T2 are the temperatures on the two sides of the material, and R is the thermal resistance of the insulation material. Thermal resistance can be determined using the formula R = L / (k * A), where L is the thickness of the material, k is the thermal conductivity, and A is the cross-sectional area. By calculating the thermal resistance and temperature difference, the heat loss through insulation can be estimated.
