Conduction angle refers to the portion of the cycle in which a device, such as a semiconductor switch or diode, conducts current. It is typically expressed as a percentage of the total cycle time. For example, a conduction angle of 60% means the device conducts for 60% of the cycle time. This parameter is important in power electronics applications to control the amount of power delivered to a load.
Changing the firing angle affects the conduction angle of the AC voltage waveform supplied to the load in AC-DC converters like controlled rectifiers. By altering the firing angle, the average output voltage and hence the power delivered to the load can be controlled, affecting the speed or intensity of the load, like in motor control applications.
Yes, thermal conduction and conduction are often used interchangeably. Thermal conduction specifically refers to the transfer of heat through a material due to a temperature difference.
The Rinne test compares bone conduction and air conduction of sound using a tuning fork. The tuning fork is initially placed on the mastoid bone behind the ear to assess bone conduction, then placed near the ear canal to assess air conduction. A normal result is when air conduction is greater than bone conduction.
Conduction
The speed of conduction depends on the type of material and the conditions it is in. For example, in a metal, conduction can be as fast as the speed of sound in that material. In general, conduction is slower than the speed of light.
The conduction angle in an SCR is the phase angle relative to the power line at which point the gate is fired to commit the anode to conduct to the cathode. By varying the conduction angle, you can change the average power transferred by the SCR.
You change the conduction angle in an SCR by delaying or advancing the point in time that you fire the gate.

Characteristics for conduction
Conduction
conduction by itself is slower to heat but conduction and convection is faster to heat
That sounds like a description of heat conduction.
It is known as: conduction.
Conduction is a phenomenon not a material.
