h bridge circuit tutorial(very very easy)!!!!!!

H-bridge is built of four switches that control the flow of current to a load. In the image above, the load is the M connecting the two sets of switches. Using one current source, you can drive current in two directions by closing two switches.H-bridge circuit could be used to operate an electrical DC motor in both forward and reversed manner as shown in the diagram. The table below shows all the possible states that the H-bridge could operate the motor in
