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.
Power dessipation is Static Power + Dynamic power
Static Power
=========
Power used by the gate when the i/p s are unaltered.only the leakage power is considered here
Dynamic power
============
Power utilized by d gate when there is a change in inputs.
Heat sink, fans etc...
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.
yes, zvzct is used to reduce the power dissipation and improve the efficiency of the circuit
Speed-Power-Product or SPP
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.
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.
Heat dissipation = (applied voltage)2 / total effective resistance of the circuit
static power dissipation dynamic power dissipation short circuit power dissipation
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
Either consumed or applied to the skin, alcohol increases heat dissipation.
heat sinks
It ended in dissipation.
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...
A: ANY part that uses current to do the work will use some of the input energy to make it operational. this energy is called dissipation of the device and it is wasted as heat
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.
heat dissipation
Basically the current should be limited to 20ma Actually the heat dissipation of the device cannot be exceeded. Some LED can be run at 100ma or more depends on the device power dissipation envelope.
