Which of the following describes the state of a solenoid valve when it is activated?

When a solenoid valve is activated, it typically transitions to the open state. This means that when electrical current flows through the solenoid coil, it generates a magnetic field that pulls a plunger or armature within the valve mechanism. This movement allows fluid to pass through the valve, resulting in an open position.

In various applications, solenoid valves are used for controlling the flow of liquids or gases. When deactivated, the valve usually remains in the closed state to prevent flow. The activation process is crucial as it allows for automated control over the fluid dynamics in a piping system, contributing to the efficiency and functionality of those systems.
