Latches and Flip Flop

Just like logic gates, the latches and flip-flops are the important elements of an electronic circuit. The logic gates form the important part of combinatorial circuits, while the latches and flip-flops form the essential part of a sequential circuit. Sequential circuits form the important concept of automata theory in electronics and electrical engineering, these circuits are a kind of logic circuit whose output depends on both present input and past inputs, that is, the input history.

The field winding of a DC generator is wound with 900 turns and has a resistance of 50 ohm. If the winding is excited from a 240 V DC source, the magnetic flux linking the coil is 4mWb. Determine the self-inductance of the coil. Show your solution.
Define the term Capacitance and Inductance? Capacitance: It is the amount of charge that is stored inside a capacitor at a given voltage. Inductance: It is defined as the property of a coil to resist any changes in electric current flowing through it. Mutual inductance happens when a secondary coil opposes current change in the primary coil. Mention what is the difference between generator and alternator? Both generator and alternator work on the same principle they convert mechanical energy into electrical energy. Generator: It converts induced emf (Electro Motive Force) into direct current, where it based on stationary magnetic field and revolving conductor which rolls on the armatures with slip rings and brushes riding against each other. Alternator: It has rotating magnetic and stationary armature for high voltage and stationary magnetic field and a rotating armature for low voltage
