Question

In defintion of electric potential.. its given that work done to bring charge from infinity to one point.

But how can we achieve that infinity? Where is that infinity??
How can a charge go infinity?

Answer 1

infinity means here that it is at a greater distance from the other charge.i.e the charge is at greater distance from the system

Answer 2

hi
this is arnav
The charge kept in any field in universe it always mentioned to be in infinity and it should be kept away from and kind of electrically charged body. To bring that charge from that field ( now that is produced by the charge itself) so the potential energy or the volts, which is required to bring that charge from that particular position to a field produced by us or in to a particular position is called the volts of energy.
Now the field which is present in any coordinate space in universe can be called as infinty.
