Answer:
they are used for electrical currents so that they can flow along the appropriate wires in the circuit
Explanation:
Relay contacts that are defined as being normally open (n.o.) have contacts that are open only if the relay coil is known to have de-energized.
<h3>What is meant by normally open contacts?</h3>
Normally open (NO) are known to be open if there is no measure of current that is flowing through a given coil but it often close as soon as the coil is said to be energized.
Note that Normally closed (NO) contacts are said to be closed only if the coil is said to be de-energized and open only if the coil is said to carry current or is known to have energized.
The role of relay contact is wide. The Relays are tools that are often used in the work of switching of control circuits and it is one that a person cannot used for power switching that has relatively bigger ampacity.
Therefore, Relay contacts that are defined as being normally open (n.o.) have contacts that are open only if the relay coil is known to have de-energized.

Los MOSFET de potencia son dispositivos de conducción unipolar. En ellos, los niveles de corriente conducida no están asociados al aumento de la concentración de portadores minoritarios, que luego son difíciles de eliminar para que el dispositivo deje de conducir.
