Voltage and Current Relationship

Question:
                How Voltage and current are related to each other?
Answer:
               

A charge is carried by electrons. The amount of charge flowing is called Current.

Voltage is potential difference. i.e. in this picture water will flow from top to bottom. Similarly, current flows from high concentration of current to low concentration of current . That is potential difference. So, the work done in moving a charge between two points is called voltage.

Power = Voltage * Current
