Q. Schematic Diagram of LED based System ?
As shown in the two schematic diagrams above, the LEDs in a seven-segment display are not isolated from each other. Rather, either all of the cathodes, or all of the anodes, are connected together into a common lead, while the other end of each LED is individually available. This means fewer electrical connections to the package, and also allows us to easily enable or disable a particular digit by controlling the common lead. There is no advantage of the common-cathode seven-segment unit over the common-anode version, or vice-versa. Each type lends itself to certain applications, configurations, and logic families.
The French scientist, Ampere, (1775- 1836), conducted a series of experiments on the force between current carrying conductors. He found that: force per metre of wire (
