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.
Wave motion is the phenomenon in which the particle/matter ruins at the point where it is. But the disturbance/energy get transferred from one point to the other. The particle ju
Q. What is dual character of light? Light behaves as particles of energy in the higher energy region as well as as waves in the lower energy region.
What is radium used for? Radium was formerly used in self-luminous paints for nuclear panels, watches, aircraft switches, clocks, and instrument dials. More than 100 former wat
Draw a picture of a moving source and the waves surrounding it according to what you observed in this experiment. How does the spacing of the wave-fronts in front of the source com
The simple equation E = mc² is not usually applicable to all these types of mass and energy, except in the special case that the total additive momentum is zero for the system unde
A box is divided into two parts of equal volume via a partition. The box is thermally insulated from the surroundings. Consider that compartment 1 contains an ideal gas A at P 0 ,
The drag on a submarine moving below from free surface (surface wave are not important) is to be determined by a test on a 1/15 scale model in a water tunnel. The velocity of the p
It is the demagnetising force which is necessary to neutralize completely the magnetism in the magnetism material after the external magnetic field is reduced to zero.
The airplane shown in the figure is to achieve "weightlessness" for a short period of time by flying along a curved path such that it's acceleration components in x direction a x
