Solid state ,those with no moving parts,coolers work using the 'Peltier effect'. DC current is passed through an array of Bismuth crystals sandwiched between two metal plates. One side of the sandwich cools whilst the other side heats. The process can be reversed.

The electric motor does not work on the principle of the amplifier and the digital signals.
What is the working principle of venturimeter?

A working principle is a regulation or rule that is used so that work can be done. This is a general phrase that can be used in any circumstance from the working principle of a motor, to the working principle of a solar cells.
It is the same piezo electric effect, the vibrations caused by the sound waves are converted into corresponding electrical signals.
The working principle of an alternator is like that of a small turbine. The alternator spins and a series of copper wires and graphite brushes inside the alternator produce electricity. That electricity is then transferred to the battery to keep it charged enough to run all of the electric parts on the vehicle.
A principle is a way of working or ethical standards.
1. Explain the working principle of a milling machine?
Get an electric scooter and bungee chord a cooler on it. i made one and it is fun!
it cools oil by circulating it thru an external cooler and works on the same principle as your radiator hot oil flows thru the cooler and is cooled by air thus "oil cooler"
