What is voltage:-\
Voltage is a potential difference between to terminals of wire, now there is another question what is potential difference. I will explain you with an example, if you place a stone on a table of any height higher than ground and other stone on ground then, the stone which is at table has higher potential than a stone which is at ground, this is because stone at the table has some energy stored while as Potential Energy.
Same is the thing with the voltage, it has a higher potential terminal and a lower potential terminal.
Now question is which thing stores energy in voltage case, answer is electrons, you know in a conductor just like a wire there are many free electrons which resides and move haphazardly inside the wire, so electron with a higher potential has more energy as compared to the electron at lower potential.
Now coming to potential difference, it is the difference of both potentials of electrons, higher the potential difference between both electrons higher will be the voltage.
They are directly proportional with each other.
It is has two types AC voltage and DC voltage, AC means alternating current while DC means direct current.
In AC there are two wires named as live and neutral but some times there is another wire named as ground. It continuously changes its direction and has frequency of 50Hz or 60Hz.
In DC there are two wire named as positive terminal and negative terminal. It don't change its direction and has zero frequency.
Usually voltage is represented as V and its standard unit is volt.
It can be found by using Ohm's law:-
V=IR
where I is the current flowing through the conductor and R is the resistance of that conductor.
What is current:-
According the the definition it is the rate of flow charges, charges may be electron and proton inside the conductor.
Now when we have created a potential difference as higher and lower potential between electrons, then an electron which is at higher potential will start moving towards the lower potential, This fllow of charges inside the conductor or wire produce a current.
Thus creating potential difference inside the conductor causes a current to flow through that conductor.
Now there is an other cause that if potential difference is same like you we supply 10 volts to both ends of wire what will happen?
Answer is simple when we have supply 10 volts on both ends of conductor then both are at same potenial which is 10 volts which means both end of conductor has same potential,so there will be no flow of current through wire.
Usually it is represented by I as current and its unit is Amphere and some times writen as amps.
It can be found be using Ohm's farmula.
I=V/R
At the end conclusion is that when ever you have a potentail difference across both ends of the conductor than there will be a flow of current inside he conductor.
Thats all hope you understand about voltage and current and their difference, if you have any query then feel free to comment, i will respond you as soon as possible.
