# What is power dissipation in resistor?

## What is power dissipation in resistor?

When an electric current passes through a conductor, some useful electrical energy is dissipated in the form of heat energy. This loss of electrical energy is due to the collision of charges with the atoms of conductor. Loss of electrical energy in unit time is referred to as “power dissipation in resistor”.

What is power dissipation?

Power dissipation is the maximum power that the MOSFET can dissipate continuously under the specified thermal conditions. It is defined between channel (ch) – case (c) or ch – ambient air (a) when mounting an infinite heat sink.

What is power dissipation in transistor?

Power dissipation At any given time, the power dissipated by a transistor is equal to the product of collector current and collector-emitter voltage. Just like resistors, transistors are rated for how many watts each can safely dissipate without sustaining damage.

### What happens to power in parallel circuit?

POWER IN PARALLEL CIRCUITS The current through a parallel branch is inversely proportional to the amount of resistance of the branch. The total power consumed in a parallel circuit is equal to the sum of the power consumed by the individual resistors.

Why do resistors dissipate power?

Any resistor in a circuit that has a voltage drop across it dissipates electrical power. This electrical power is converted into heat energy hence all resistors have a power rating. This is the maximum power that can be dissipated from the resistor without it burning out.

What is the difference between power consumption and power dissipation?

Power consumption means the total power consumption of that device. Power dissipation stands for the part of the power that is consumed by things not related to the desired tasks. MOSFET represents Metal oxide semiconductor field effect transistors and MOSFETS are now widely used in electrical components.
