Rules of Boolean algebra

Rules of Boolean algebra
Just as we required two basic mathematical operation i.e Addition and subtraction for the mathematical manipulation of ordinary quantities which can possess all continuous value, we require a special algebra known as Boolean algebra for the manipulation of the quantities which have values 0 and 1 and are known as Boolean variables. A unique character of Boolean algebra is that variables used in it can assume only one of the two values i.e. either 0 or 1. Rules Boolean algebra is based on three basic operation namely AND operation, OR operation and NOT operation.

What is digital Logic gates of electronics

Basic logic gate
The electronic circuit which makes logic decisions is called a digital logic gate. It has one out put and one or more out puts. The out put signal appears only for certain combinations of input signals. Logic gates are the basic building blocks from which most of the digital systems are built up. They implement the hard logic function based on the logical algebra developed by George boole which is called Boolean algebra.

The logic gate is described by definition , symbol, Boolean expression and truth table.

Biot- Savart Law

The biot-savart law state that magnitude of magnetic field at a point due to current distribution is directly proportional to amount of current  and effective length of conductor and inversely proportional to square of distance between current distribution and point.
