Electronics

Everyone today is exposed to electronic devices. The computer revolution is a most famous example.  A study of electronics starts with electricity mainly focusing to AC and DC current and some of the basic electronics components.  And also this includes Ohm's law and other basic principles of electricity .  By referring various books on electronics  you can gain more knowledge of these basic electronics concepts. Let's move on Ohm's law and types of current.

Ohm's law :

Ohm's Law deals with the relationship between voltage(V) and current(I) in an ideal conductor. This relationship states that:
The potential difference (voltage-V) across an ideal conductor is proportional to the current (I)through it.The constant of proportionality is called the "resistance" and it denote by R.
through this definition Ohm's law can be:
    V = I R
where V is the potential difference between two points which include a resistance R. I is the current flowing through the resistance.
