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 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.

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 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.
