What is Falling Film Evaporator? Working Principle, Diagram & Applications
Falling film Evaporator is a type of long tube evaporator, in which high velocity feed enters from the top of the evaporator and flows down the walls, hence the apparatus is named as Falling film evaporator.

What is an Autotransformer? Connection Diagram, Symbol, Construction, Working Principle & Applications
Fig. 1: Autotransformer (Construction & Symbol).
The normal transformer has separate primary and secondary windings. But the autotransformer is a special transformer in which a part of winding is common for the primary and secondary windings. The construction of an autotransformer is as shown in Fig. 1. It consists of only one winding wound on a laminated magnetic core, with a rotary movable contact. Thus from the autotransformer three terminals are brought out for connection. The autotransformer can operate as a step down or a step up transformer.
What is DC Series Motor? Working, Diagram, Characteristics & Applications
Connection diagram of DC Series Motor
Fig. 1: DC Series Motor.
In the DC series motor, the armature and field windings are connected in series with each other as shown in Fig. 1. The resistance of the series field winding (Rs) is much smaller as compared to that of the armature resistance (Ra).
What is Voltage Follower using Op-Amp? Circuit Diagram, Derivation & Working
The circuit in which output voltage is exactly equal and in-phase with its input, then the circuit is known as voltage follower.
A non-inverting amplifier, whose gain is equal to 1, acts as a voltage follower. The circuit includes an op-amp and a wire connecting the output and input terminals. A non- inverting amplifier configured as voltage follower is illustrated in figure below.
