When the control circuit power is turned ON, are M1 and M2 energized?

The correct answer indicates that when the control circuit power is turned ON, M1 and M2 are not energized. In many control circuits, components are only activated when specific conditions are met, such as the presence of an initiating signal or an operator's action.

For instance, if M1 and M2 represent motor starters or components within a control circuit, the energization of these elements often depends on additional parameters, such as push buttons, timers, or relays. Simply turning on the control circuit power does not guarantee that both M1 and M2 will be energized without the necessary conditions being satisfied.

So, unless there is an active command or condition allowing M1 and M2 to be energized as soon as power is applied, it is accurate to state that they remain inactive until further action is taken. This understanding helps in troubleshooting and designing control circuits effectively.
