The basic principle that rheostats use is Ohm's law, which states that current is inversely proportional to resistance for a given voltage. This means the current decreases as the resistance increases or it increases as the resistance decreases. Current enters the rheostat through one of its terminals, flows through the wire coil and contact, and exits through the other terminal. Rheostats do not have polarity and operate the same when the terminals are reversed. Three-terminal potentiometers can be used as rheostats by connecting the unused third terminal to the contact terminal.

The electric motor does not work on the principle of the amplifier and the digital signals.
1. Because water conducts electric currents and this would prevent the electric circuits working properly. 2. Wet skin is a very good conductor of electric current and there is a high risk of an electric shock.

Thomas Edison invented the Parallel circuit while working on the electric lightbulb
What is the working principle of venturimeter?
You cannot discover something that does not exist - the principle of integrated circuits was first suggested and proven in 1958 by Jack Kilby working for Texas Instruments.

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.
