The generator is an application of electromagnetic induction. It works on the principle that when a wire is moved in a magnetic field, then the current is induced in the coil. A rectangular coil is made to rotate rapidly in the magnetic field between the poles of a horse shoe ty..
Principle Underlying the Working of a Solar Cell
Semiconductors whose conductivity is more than insulators and less than metals are used in electronic devices. The conductivity of the semiconductors increase when light falls on it. Wafers of doped semiconductors are so arranged that when sunlight falls on the arrangement, potential differences ar..
Principle of Moments
If a body is in equilibrium under the action of a number of forces, then the algebraic sum of the moments of the forces about any point is equal to zero. In other words, the sum of the clockwise moments equals sum of the anticlockwise moments when the body is in equilibrium. ..

Principle of Fax Machine - The essential parts of a fax system are the transmitting devices that translate the graphic material into electrical impulses according to a set pattern, and a synchronized receiving device that retranslates these impulses and prints that. In a typical system, t..
Physical Concept of Uncertainty Principle
To determine the position of an object, we must be able to see the object. This can be done with the help of light of suitable wavelength. When a beam of light falls on an object, the photons of this incident light are scattered by the object and the reflected light enters our eye. ..
Common Balance
This balance consists of a beam and two scale pans (shown in figure below), the beam being balanced at its mid point on a knife-edge. The scale pans also hang on knife edges and rest on the base board. When the balance is not in use the beam..

It is a matter of common experience that bodies appear lighter when immersed in water or any other liquid. While bathing we notice that the mug of water suddenly appears heavier as soon as it comes above the water surface. Similarly, when a fish is pulled out of water, it appears to be heavier in a..

Tutors are very well educated who knows what they are doing and is very good at math. Also I like the way they teach me - Baker
All the solutions that these tutors give are correct I got a 83% on my last quiz, Thank you so much - Giara
Very helpful lesson about Algebra good explaining. I'm done with all my assignment questions. Thank you tutor
Me and my younger brother have joined tutorvista tutoring and its helping us a lot in studies, now we can study whenever we want.
