Chapter 7, Problem 1RQ
Refer to the circuit shown in Figure 7-10. If wire number 11 were disconnected at the normally open auxiliary M contact, how would the circuit operate?
Figure 7-10 Numbers are placed beside all components.
Expert Solution & Answer
To determine
Identify how the circuit would operate.
Explanation of Solution
In the given circuit, the auxiliary contact M is connected in parallel to the start button. The operation of the circuit after disconnecting the auxiliary contact M will be as follows:
- When the start button is pressed, the coil gets energized and the circuit is closed.
- After the start button is released, there is no closed circuit, and this leads to an open circuit.
