Question 317Electricity & Electronics - QMED
70% to passAs shown in figure "B" of the illustration, which of the operations listed will happen when the 'jog button' is pushed? Illustration EL-0010
ACoil 'CR' energizes thus closing both 'CR' contacts.
BCoil 'CR' energizes thus opening both 'CR' contacts.
CCoil "M" energizes thus closing contact "M".
DCoil "M" energizes thus opening contact "M".
AI Explanation
The correct answer is C) Coil "M" energizes thus closing contact "M". When the 'jog button' is pushed, it energizes coil "M", which in turn closes the contact "M" as shown in the illustration. This is the typical operation of a jog button in an electrical circuit - it temporarily energizes a control component (in this case, coil "M") to initiate a specific action, such as closing a contact. The other answer choices are incorrect because they do not accurately describe the operation depicted in the illustration. Coil "CR" does not energize, and its contacts do not open or close, when the jog button is pushed.
