What is Voltage and current?

What is Voltage?

When two charge distributions are separated by a distance,there exists an electrical force between the two depending on the kinds of those charges like whether opposite or attraction force.Let say,those charges are opposite.SO,when we put a small positive charge between their electric field,that charge is influenced by those charges.Ok?that charge is attracted because of negative charge and is repulsed by the positive charge.So,the charge will move between them.So,that small + charge will have changing potential energy.This change in potential energy is equivalent to the work done by positive charge.If we divide that work done by amount of charge,we will get what we called "Voltage".
Voltage is defined as the amount of energy required to move a unit of electric charge from one place to another.Actually,My opinion is it means how that can make electrons moved to get current.

*electric field exits around of every charge.
Current?

Current represents the amount of electrons or charges(Delta Q) crossing a cross-sectional area in one unit time.
I=delta Q/delta t
Now we have kept in touch what is electricity,potential difference,Voltage,electric field and current.I will continue to discuss about the parts of circuit like resistors,transistors..........
