Voltage:
Voltage is the electrical equivalent of mechanical potential. If a person drops a rock from the first storey of a building, the velocity it will reach when dropped will be fairly small. However, if the rock is dropped from the twentieth floor, it will have reached a much greater velocity on reaching the ground. On the twentieth floor the rock had much more potential energy.
The potential energy of an electrical supply is given by its voltage. The greater the voltage of a supply source, the greater its potential to produce a current flow. Thus, a 115 volt supply has 115 times the potential to produce a current flow than a 1 volt supply.
POTENTIAL
If one coulomb of electrons is added to a body and one joule of work has been done, then the body will acquire of potential of - 1 volt. If the electrons had been removed, then the body would have acquired a potential of +1 volt. The unit of potential is the volt.
All the traveling waves satisfy a differential equation which is known as the wave equation
If a particle is projected vertically upward in a constant gravitational field with an initial speed v 0 . If there is a retarding force proportional to the square of the instantan
In this problem we will consider a vapor fluid interface on top of a solid surface. A schematic is shown below: This is a zoomed-in picture of the edge of a liquid droplet
Electric Current: Electric current may be described as the rate of flow of charge. I=q/T Where, I = electric current q = charge T = time The unit of current i
The magnitude of the force vector F is 270 newtons. They component of this vector is directed along the +y axis and has magnitude of 150 N. The x component is directed along the +x
Conductor: Conductors are those substances which permit electric current to passes easily by them. e.g. Metal, impure, water etc.
One of the most important theorems in the quantum physics in the Pauli Exclusion Principle, which is based on the experiment observations. The principle explains that “No two elect
