Power isn't really dissipated in a circuit. It's energythat is dissipated. So the expression, 'power dissipation', really means is the 'rate of energy dissipation'.
So, when an engineer asks, "What is the power dissipation?", what he is actually means is "What is the rate of energy dissipation?"
What is energy dissipation? Well, work is done whenever a current flows through a conductor; this increases the internal energy of that conductor which, in turn, causes its temperature to rise. Because the temperature of the conductor is higher than the surrounding temperature, energy is lost to the surroundings through heat transfer.

What is the power dissipation for TTL?
power dissipation of a logic circuit is usually defined as the supply power required for the gate to operate with a 50% duty cycle at a specific frequency.
Circuit of soft switching technique using zvzct in buck converter?
yes, zvzct is used to reduce the power dissipation and improve the efficiency of the circuit
What measures the performance of a logic circuit using propagation delay and power dissipation?
Speed-Power-Product or SPP
Why are printed circuit boards used when constructing an electronic circuit?
It has a number of purposes. It provides a solid surface to mount the other components onto. It creates the connections in a neat and organized way that would not be possible if you just soldered each component to the next one. It also maintains the spacing to allow heat dissipation.
What is produced when there is resistance to the flow of electrons?
It depends on the nature of the device acting as the resistor. All basic circuit components act as resistors. Resistors dissipate energy from the current in the form of heat. Capacitors store energy in a electric field. Inductors create a magnetic field.In practice in general, heat dissipation is present in most resistive devices (including circuit wires). So common, in fact, that we call it "internal resistance". But that is effectively how we use electricity: by resisting its flow.
What is the mathematical relationship between heat dissipation and applied voltage?
Heat dissipation is directly proportional to the square of the applied voltage according to Joule's Law. This means that as the voltage increases, the heat dissipated in a circuit also increases quadratically. The relationship is represented by the formula: Heat dissipation = V^2/R, where V is the voltage and R is the resistance in the circuit.
Term used to describe how much heat a circuit dissipates?
Power dissipation.
What are the different types of power dissipation?
static power dissipation dynamic power dissipation short circuit power dissipation
What term is used to describe how much heat a circut dissipates?
The term used to describe how much heat a circuit dissipates is "power dissipation." It refers to the amount of power that is converted into heat as the circuit operates, usually measured in watts.
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
Can alcohol alter heat dissipation?
Either consumed or applied to the skin, alcohol increases heat dissipation.
Is heat load and heat dissipation same?
No, heat load refers to the amount of heat energy that a system generates or absorbs, while heat dissipation is the process by which this heat energy is transferred or released into the surrounding environment. Heat load is the input, while heat dissipation is the output.
Is heat rejection the same as heat dissipation?
No, heat rejection and heat dissipation are not the same. Heat rejection refers to the process of transferring heat from one place to another, such as releasing heat from a system into the surroundings. Heat dissipation, on the other hand, is the dispersion of heat within a system to lower its temperature.
What is used for heat dissipation in ICs?
heat sinks
How did heat end?
It ended in dissipation.
What are the limitations of norton's theorem?
norton's theorem is valid only for linear elements.. The power dissipation across norton equivalent circuit in not identical with the power dissipation in real system circuit...
What makes a current lower and generates more heat?
The resistance of the electrical conductor, eg a wire, reduces the current which can flow in the circuit. The remaining current which does flow generates heat, representing the electrical energy which has been lost in overcoming the resistance.
