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.
When the electron is known energy from external source, it goes to higher energy level. This process is called as excitation. The minimum energy needed to excite an atom is know
Q. Describe the isotopes? Answer:- An atom of an element that has a diverse number of neutrons in its nucleus to other atoms of the element.
The angular displacement of a body is a function of time and giving by equation h=10+3t+6t square,where t is in seconds.determine the angular velocity, acceleration when t=5seconds
is there any Law of Physics acting in a weighted object placed in a corrugated paper and the paper can actually support it well thanky you :)
