I am not able to understand electric currents.
Can anyone explain?
Perhaps if you could specify exactly what is bothering you, ....... Otherwise, I will be just repeating what you can read from a textbook
You should not expect to be taught broad subject areas in this forum. It is why such areas are covered in textbooks and in classes. The most effective way to learn from this forum is when you have specific topic and areas. You have to make an effort to narrow down what exactly it is that you don't understand.
