Subject:Electronics Engineering What is the main constructional difference between D-type and E-type MOSFET?

DA shunt generator is used to charge a battery of 100 cells in series. If each cell has a terminal p.d. of 2.5V at the completion of charge and is of internal resistance 0.001 Q calcu- Cate the e.m.f. to be generated to give a charging current of 15A at the end of charge. Assume that the armature and field resistances are 0.2 2 and 200 2 respectively and the cables onnecting the generator to the battery have a resistance of 0.6 Q.
