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.
Regard as a positively charged particle in a circuit. As it moves during a resistor in the circuit the positively charged particle moves from a point one end of the resistor in the
Inertia with a spade Scoop up a spadeful of dry earth. Now pitch the earth away from you. View that when the spade stops the earth flies on due to inertia.
In a non-uniform magnetic material, these substances move from stronger parts of the field to the weaker parts.why?
When a body or a moving particle repeats its motion along an exact path after regular parts of time, its rotation is said to be Periodic Motion and interval of time is known as per
