Depending upon the source of electrical energy, there are two types of electric motors: A.C. Motors: Motor that converts alternating current energy into mechanical energy is called A.C. motor. D.C. Motors: Motor that converts direct current energy into mechanical energy is called D.C. motor.OWER LOSSES IN A DC MOTOR. The basic function of dc motor is to convert electrical energy into mechanical energy. Whole of the input energy is not converted into useful output energy but a part of the input energy is converted into heat and the same is lost.
Concatenation in Java is the operation of joining two strings together. You can join strings using either the addition (+) operator or the Stringâs concat() method.
The process of merging data literals is one of the core applications of concatenation. The concatenation syntax in different programming languages is given below. In addition to strings, concatenation can be applied to any other data type, including objects.
