In general, a valve (as in thermionic), a tap or gate valve (as for water).
Or perhaps just a constriction.
Resistance in an electrical circuit.
A shaped nozzle is important for some purposes such as a garden hose, or as in sand blasting process.
I think it is a capacitor but I am not entirely sure
Traffic lights
Swith
A device for controlling the flow of liquid, as from a pipe; tap
It's fancy wording for one of two things. (1) You ran a stop sign. (2) You ran a red light. Either one is a traffic violation, and gets you a ticket. Any device that can legally be used to control traffic such as a sign or a flashing light is also a traffic control device.
False. A device that is used to open the circuit when the current flow is too great is a circuit breaker or fuse.A disconnect switch is a manual device that isolates or turns off the load.
It is called a pressure balancing valve, usually used in shower applications. Also a preset temperature mixing valve could be used depending upon what you need the device to do.
Diode is a Two terminal device which allows flow of curent in forward direction that means it converts DC to AC
Controlling movement and flow of traffic
Switch
IC 555 is a simple timer integrated circuit device and used for traffic light timing to control traffic flow.
A device for controlling the flow of various liquids.
A device for controlling the flow of liquid, as from a pipe; tap
A mastic regulator is a pressure controlling device that smooths out the flow of high viscosity fluids in a pressurized system. Generally used in the industrial application of sealants and other caulking.
A switch is a device that stops and starts current flow in a circuit.
Resistors are used to control current flow.
The flow of electricity (known as current) is measured in amps by an ammeter.
