Yes anything that needs less than 40 amps is OK but the total current must not exceed 40 amps.
If the question is, can I wire a switch to an existing light fixture (and I must assume that it's something like a pull-chain light fixture), the answer is yes.If the question is, "how do I wire a switch to an existing light fixture that has no external switch", the answer is, "in series".The attached web site gives simple instructions on how to wire a basic light switch to an existing light.See sources and related links below
Connect the white wire from the European oven to the white wire in the US receptacle. Connect the black wire from the European oven to the black wire in the US receptacle. Connect the green wire from the European oven to the bare wire in the US receptacle. The green wire serves as the ground wire since you don't have a separate ground wire in the US receptacle.
Hard wired means that there is no plug and receptacle in the circuit powering the dryer. What you will find is a metal jacketed cable that will come out of the wall or floor and go right into the dryer.
Hard wired smoke detectors have to have a junction box behind them. These detectors use 120 volts as a working voltage. These types of detectors should be wired with 3 conductor #14 wire. The detector uses the black and white wires for the 120 volt source. Detectors these days have an output signal wire that can be connected to other detectors so that if one trips it will sound the alarm in other detectors that are on the same circuit. This output wire can be connected to other detectors by the third red wire in the 3 conductor cable.
In an oven. The "hot" wire is in series with the ove thermostat and provides an isolated circuit for turning on the oven element(s).
50 amp breaker wired with AWG # 6 wire.
Hard wiring something is when you terminate the device or equipment directly with the cable/wires that are coming from the panel. Say for example: You have a 40' length of 10-3 M.C. cable (or similar) coming from your panel to feed power to the oven. In the case that the oven needs to be hard wired , there will be a junction box in the back , bottom, portion of the oven or an insulated cord with uncapped wires hanging out in which (either way) you need to splice the 10-3 cable to the wire ends of the oven inside that junction box (or the junction box that is installed in the wall). If the oven didn't need to be hard wired than you would normally install a 30-60 amp receptacle/outlet in a 4x4 box in the wall and you would terminate the 10-3 cable to it and the oven would come with a cord and plug that you would just plug into the wall. So, an easy way to think of it is: If the equipment needs to be hard wired than it will not have a plug on the end of the cord/cable. And if it doesn't need to be hard wired than you will just plug it into an outlet.

Wall receptacles are wired in parallel. black to black, white to white, ground to ground.
A 30 amp breaker run 75 feet would require you use AWG #10 wire. But, an oven normally pulls more that 30 amps and I would not use #10 wire on a 30 amp breaker for an oven. Normally any newer oven is wired with AWG #6 gauge wire on a 50 amp circuit breaker so the breaker will not trip during heavy use of the oven. Some older ovens could use a #8 wire on a 40 amp breaker.
Yes the electric wire needs to run all the way around.
Most motors aren't wired with solid wire. Typically only alternators or electric motors have solid wire.
if you wire a money, why can't it be that the wire transfer charge be collected to the money which is to be wired itself?
Depends on the load of the oven. More than likely it will require AWG #6 but you need to read the electrical requirements for that particular oven.
Wired networks have a wire that connects them to an internet port, wireLESS networks do not.

If wired properly the ridged wire is the neutral.
