The state of a valve or pump when electrical current is applied to the coil.

An object which has electricity flowing through it.

Electrically connected to a source of potential difference, or electrically charged so as to have a potential different from that of the ground.

similar terms meaning that a voltage is present that can cause a current, so there is a possibility of getting shocked

When current is flowing though the coil and resulting magnetic flux is sufficient to draw the plunger up against the stop.

Being electrically connected to a voltage source so the device is activated.
