I don't believe what you are saying is possible in full. The closet i have ever come to a "wireless" circuit is having a power supply run a fan on a motor that would then blow wind against another fan that was attached to a generator, which then fed into a light bulb and finally back to the power supply. The energy did not travel through a wire, but instead by air. But it is unlikely that there is a 100% wireless circuit.
How to make a wireless remote control car plz give circuit diagram
I have never heard of an electrical term "build" in an electrical circuit.
Yo don't.
The things needed to build a circuit are:Circuit elements like resistor capacitors, inductors etcConnectors (cables)A source
You build an electronic device to control a transistor switch that causes a mechanical device to push the switch. Now days we bypass the mechanical switch and the circuit can do the switching.
Three main components that are needed to build a circuit will be a power source. This supplies the circuit with a voltage to operate. A load to make the current flow through the circuit, and conductors to join these two devices together to carry the current.
I purchased my wireless adapter from Walmart, but I am sure you can purchase them at any electronic retail store like Circuit City or Best Buy.
iron nickel or cobalt
yes. because it is easy and more powerful to access
exactly what you mean in question. wireless is a broad subject for example wireless LANs enable you to build computer networks without wires. IEEE standards for wireless LANs are 802.11a (5ghz) and 802.11b/g (2.4ghz)
Could you build a working electric circuit using glass rods as the conductors? Why or why not?
You can find prepaid wireless internet at your local Best Buy or Circuit City. They work by plugging in a usb drive with a wireless card into your usb port and you will set it up and after that, it will work.
