Potential free contacts (also called "dry contacts") are simply contacts which are physically operated with the main device, but not electrically connected to it. For example a motor contactor often has auxiliary contacts that are operated by the main coil and open and close at the same time as the main contacts but are not used for control of the motor starter. If they are connected to an outside circuit to indicate the status of the starter without being powered by the motor supply they would be considered potential free contacts.
These type also called Signal-Contacts.
In case of relays and switches if the common/pole is connected internally to a given potential like a 110V phase etc., the contact is not POTENTIAL FREE but if both the common and the normall open (and at time also the normally closed) contacts are presented to the user for connecting in his system as he pleases,the contact is said to be "potential-free".
A: SURE it can while open it will measure the potential when closed it will measure the small voltage drop due to the resistance if any.

Keeps the current in the conductor. Without the insulation on a conductor the current can and will leave the intended path in the electrical circuit if it comes in contact with some other conductive path if there is a difference of potential.
V which abbreviates the word volt, which is the unit of measure of the difference in electromotive force (EMF), (or electric potential) between two points of contact; the resulting voltage difference could be direct current (DC) or alternating current (AC) depending on the source of the voltage difference.
The definition of electricity is the flow of charge. Usually our charges will be carried by free-flowing electrons. Negatively-charged electrons are loosely held to atoms of conductive materials. With a little push we can free electrons from atoms and get them to flow in a generally uniform direction. A closed circuit of conductive material provides a path for electrons to continuously flow. The charges are propelled by an electric field. We need a source of electric potential (voltage), which pushes electrons from a point of low potential energy to higher potential energy.

potetial free contacts is a contact of switch or relay that use an external supply, its contact only used to joined tow equipements by electrical supply. mamoun elrayah sudan-gnpoc

Come prepared when ever dealing with a high level monster.
A lead magnet is an incentive, such as a coupon code or a free ebook download that potential customers receive in exchange for their contact information.
A manufacturing organization might use toll-free numbers for sales and customer service to encourage customers and potential customers to contact them, knowing the call is free.
If your reference has a prior relationship with the potential employer then the contact would make sense. If not, no.
You cannot contact professional dancers for free.
The contact potential of a pn-junction diode is signified by the turn-on or barrier voltage, which is the voltage beyond which non-negligible current con be measured flowing in the forward-bias direction. To put it simply, one can run a variable potential difference across a diode in it forward-bias direction until one measures a current. That is the contact potential of the diode. Theoretically, the contact potential is a function of the temperature and doping concentration, and intrinsic hole-electron pair concentrations. However, in the real world, there maybe other factors that will affect the contact potential of a diode.

There are no safe websites where you can get free criminal background checks. You should contact your local courthouse and file for a criminal background check, as you might for potential employees. Sites that provide this service for a fee are generally not reliable or accurate.
