The ladder diagram for the circuit shown below is Correct Answer <img alt="F1 Shubham B 17-12-21 Savita D37" src="//storage.googleapis.com/tb-img/production/21/12/F1_Shubham%20B_17-12-21_Savita_D37.png" style="width: 142px; height: 18px;">

Concept:

Alternative paths provided by vertical paths from the main rung of a ladder diagram, that is, paths in parallel, represent logical OR operations.

The below figure shows an OR logic gate system on a ladder diagram

The ladder diagram starts with ||, normally open contacts labeled input A, to represent switch A, and in parallel with it ||, normally open contacts labeled input B, to represent switch B.

Either input A or input B must be closed for the output to be energized. The line then terminates with ( ) to represent the output.

On a ladder diagram, contacts in a horizontal rung, that is, contacts in series, represent the logical AND operations.

Solution:

The given circuit is 

Shortcut TrickA switch is in series with the relay coil, so normally open contacts will be in series with the circle.
