Referring to the circuit shown in Figure 23–1, would it be possible to change the components that have been numbered with an 8 to a number 9, and the components that have been numbered with a 9 to a number 8, without affecting the operation of the circuit?
Whether it is possible to change the components that are numbered with an
Explanation of Solution
Consider that the schematic diagram shows the circuit operation and not the wiring of the components. The wiring diagram is drawn that is based on how the components are numbered, thus it shows how the wiring is done.
The components in schematic diagrams are numbered in the sequence of connection order.
Refer to the circuit shown in Figure 23-1 as shown in the text book.
Consider that the machine consist of the three motors and when it is started there is a time delay of 10 sec. As the start button is pressed the circuit gets completed with the start button and the motor coil and
This shows that
The number changing of the components is not practical as each of the components is assigned a specific number in a schematic diagram.
Consider that the two relays one and two are interchanged with their position then, then, the motor M3 works when the relay TR1 is closed and the M2 works only when the TR2 is closed.
Thus, the changing of the component numbers
