the function of the control device is that you can know if the circuit is on or off
Yes I have one that runs on a 30 amp circuit.
A fuse places a limit on the amount of current that can be drawn by an electric circuit by opening (blowing or melting) when the current exceeds a preset limit. This protects the circuit and the surroundings from fire or damage in the case of an overload or short circuit.
Yes. The rating of a relay is how much current it can switch on and off, not how much it uses or must have.
There are many variables that affect the ratings of electrical circuits but in general: If you are asking about residential branch circuit ratings, they are listed in amps and protected by a fuse or breaker. For example, a typical residential lighting circuit is usually a 15 amp / 120 volt circuit. It will be protected by a 15 amp overcurrent device (breaker or fuse) and all components of the circuit (wire etc) must be rated for at least 15 amps. Common residential circuit ratings: 15 amp / 120 volt - lighting and receptacles 20 amp / 120 volt - bathroom, kitchen, dining room, workshop etc. receptacles 30 amp / 240 volt - electric dryer, electric water heater 40 or 50 amp / 240 volt - electric stove For minimum conductor (wire) sizing, the National Electric Code recognizes many variables that affect the ampacity (number of amps) a wire can safely carry. But in most residential circuits the following copper conductors are used: 15 amp - #14 American Wire Gauge (AWG) 20 amp - #12 AWG 30 amp - #10 AWG 40 amp - #8 AWG 50 amp - #6 AWG Aluminum is typically not used in the smaller sizes, though you may find #6 AWG used for larger (40 amp) loads

the function of a resister is to lower the voltage.
A voltmeter is a device to measure the voltage in a electric circuit, and must have be connected in parallel to it.
The function of a capacitor or an electric circuit is to store energy. It keeps this energy stored until it is need for release at a later time.
it's function is to supply energy(electric)
To trip when current is in excess of 15 amps and protect the circuit components.
I have never heard of an electrical term "build" in an electrical circuit.
The function of a light bulb in an electric circuit is that it turns electrical energy into light.

To provide electricity for the bulb to light up.
