What is the difference between power consumption and power dissipation?
A: POWER consumption is total power usage power dissipation is wasted power in the form of heat, IR drop and so on.
Explain the need for thermal analysis and the need for effective heat dissipation for an electronic circuit?
Thermal analysis are used to prevent the electronics circuit being damaged, such as heat sinks are used to absorb the heat which is created by the components to protect the sensitive components
Do power stations use heat to generate electricity?
Yes most power stations do use heat to generate electricity. Heat energy of the fuel (e.g. burning coal, burning oil, nuclear fission) is utilized to heat water present in the boiler. This heating generates steam, which is then utilized to run the turbine. However some power stations get the energy to generate electricity without using heat (e.g. hydroelectric dams, wind power, sea wave power, solar cell generation systems).
What is resistance power?
All resistances will emit heat energy when a current flows. The heat production rate (or power) can be found by any of these formulas: Power = Current * Voltage Power = Current2 * Resistance Power = Voltage2 / Resistance. Power is given in Watts when Current is in Amps, Voltage in Volts, and Resistance in Ohms.
The ability or power to transmit heat electricity or sound?
conductivity
Why power electronic device symbols are not circled?
Because the power electronics devices can not be packed, they should always be in touch with air for heat release.
Is heat energy always useful?
No, heat energy is not always useful. In some situations, like in the case of unwanted heat in electronics causing overheating, heat energy can be detrimental. However, in many cases, heat energy is harnessed for various purposes such as cooking, heating buildings, and generating electricity.
In a practical machine the power output is equal to the power input?
No, because of inefficiencies which usually cause heat, or heat in unwanted places. Or wear of parts. The total power in always appears somwhere in some form, not always where it is wanted.
How does give give out heat?
All energy converters will give out heat. Tv's will get energy from their source and convert it to sound, light and heat energy.
Why would the catalytic converters get red hot and glow as well as effect power on a 2001 Yukon XL with a 5.3 liter Vortec engine?
Excess fuel can super-heat the converter causing the converter to meltdown. The excess fuel can be the result of many possible engine malfunctions. The converter meltdown would result in blocked exhaust flow resulting in power loss. At this point the converters are junk. Do not just replace the converters without correcting the cause.
How does television set give out heat?
All energy converters will give out heat. Tv's will get energy from their source and convert it to sound, light and heat energy.
Why do you use resistor in electronics?
we use resistors to offer opposition to the flow of electric current. Resistors absorbs power from the circuit and convert it into heat that is why they are normally rated for the maximum amount of power that they can salfely handle
Why do you need power?
We need power to live like we need power for heat to get water run your car keep things cold we would always need it
Does it damage electronics to be shipped across Mojave desert in heat?
NO!
What are the main functions of heat sink?
The main purpose of a heat sink is to expel heat from a generating source. Heat sinks work through the process of conductive and convection heat transfer. Heat sinks are a passive form of cooling, as they have no moving parts and require no power.
Does heat always attract more heat?
Heat does not always attract more heat. In fact, heat will always be attracted by something that contains allot less heat than the original amount of heat.
What type of resistors carry relatively high electric currents?
Power resistors are designed to carry high electric currents due to their ability to dissipate heat effectively. These resistors are commonly used in applications where high power levels need to be handled, such as in power supplies, industrial equipment, and power electronics. They often have a large physical size and are built to withstand the heat generated by the current passing through them.
