Question

In the Delta or Mesh connection, there will be __________ number of common terminals.

(a) 1

(b) 2

(c) 3

(d) 0

I had been asked this question by my college professor while I was bunking the class.

The query is from Inter Connection of Three-Phase Sources and Loads in chapter Polyphase Circuits of Network Theory

Answer 1

The correct option is (d) 0

The explanation is: The three line conductors are taken from the three junctions of the mesh or delta connection to feed the three phase load. This constitutes a three phase, three wire, delta connected system. In the Delta or Mesh connection, there will be zero number of common terminals. Number of common terminals = 0.
