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
