Hello,
Will someone please explain me whether my understanding about voltage, potential difference and current are correct?
According to me,
Voltage is like the food we eat , which is a chief source of energy. similarly in a conductor free electrons move randomly in all possible directions. so in order to make the electron move in one direction we need to supply an energy .that is nothing but voltage.
Potential difference:
Consider a man standing at point a he possess 500calories of energy.when he walks for 5m and reaches position b he possess 480 calories of energy.so he lost 20 calories of energy that is the potential difference.
It is applicable for electron too
When an electron is at position a it possess 5v of energy(potential).when it moves and reaches b it possess 3v of energy(potential).thus the energy lost (5-3)v=2 volt ,is the potential difference.
Current:
It is the number of electrons crossing position a at a unit time.
If I were wrong please correct me.
Thanks in advance.
