what is the diffrence between voltage and current?
Answer Posted / mack
CURRENT:- Electricity is the flow of free electrons in a
conductor from one atom to other atom in same general
direction. this flow of electron refered as current and its
designated by the symbol "I",
Voltage:- Voltage is the force applied to the conductor
that causes electric current to flow. its designated by "V".
