The modulation factor of the modulation index in a frequency modulation is defined as the ratio of the frequency deviation to the modulating... View Article
The internal resistance of a battery descreases with the increase in temperature due to the increased electron mobility at higher temperatures.... View Article
In an equipotential surface all the charges and points are equidistant from each other. As the charges are equal and opposite to each other, they... View Article
When longitudinal waves propagate through a medium, the medium are displaced in a direction parallel to energy transport. The energy is... View Article
Attraction is a force between two or more dissimilar or unlike charges. Two charges of dissimilar characteristics pull towards each other.... View Article
Higher the kinetic energy, faster the vibration and the particles move around faster. Solids have the lowest kinetic energy as they are tightly... View Article
If the galvanometer and the cell are interchanged then the balance point remains unchanged. Hence, the galvanometer will not show any current and... View Article
