0Electricity: Form of energy which is generated through charges. Charges are of two types: positive and negative.
Same charges repel each other where as different charges repel each other.
Unit of charge is columb. Denoted by C. We can write charge as Q.
Electric potential amount if work done In moving a unit positive charge from infinity to any point in an electric field.
V = W/Q.
V is potential difference.
W = work done
Q = charge.
Important question:
Define 1 volt?
1 volt is Define as the 1 Joule of work done used in moving one columb of charge in an electrical field..
1V = 1J/1C.
This is one topic. I will post each topic soon. Any queries from student.
