There is no mechanical connection in between field and
armature windings . The winding of the field is wound on the
stator cores while that of the armature is wound on rotor
cores. There must be a narrow gap in between the stator and
rotor cores ( say 2mm ) so as to rotate the rotor freely .

how does the terminal voltage of transmission lines increase when a capacitor is connected???? This happens not only in transmission lines but also in all circuits. How??? When a capacitor is connected in a transmission line, capacitor also takes energy from the same supply. But how is it able to increase the terminal voltage??? Practically What sequence of events happen during increase in voltage???
