Question

Rate of energy dissipation is measured in
(A) Watt
(B) Joule
(C) Weber
(D) Joule/coulomb

Answer 1

Energy dissipation is just a transfer of energy from one place to another. The unit of Rate of energy dissipation will also remain the same as measuring the unit of energy. So use this concept for the determination of the correct answer from the given option.

Complete step by step answer:
In general, the term energy is the potential for causing changes by doing work. The better conversion of energy gives us more work, and the energy causes things to happen; for example, the sun's energy through sunlight makes plants grow; the energy we obtained from the food allows us to move, and the fuel gives energy to the engines for the desired results. We can change the form of energy from one kind to another, but we can not destroy or create it. Different kinds of energies exist in nature like heat energy, mechanical energy, chemical energy, etc. The standard unit used for the measurement of energy is joule. When any object dissipates energy from its body, it transfers some energy from its body to its surroundings. So the measuring unit of energy dissipation also remains the same as energy.
Therefore, the rate of energy dissipation is measured in Watt.

Note: Remember the measuring unit of energy because from this, we can obtain the unit of energy dissipation rate. Also, remember that when some object does work for the desired result, it can not use its all energy in the desired result, some portion of the energy dissipated into the surrounding.
