Usually there are 3 wires.
The Black wire or the "hot wire" this is connected to a circuit breaker or a fuse.
The White wire returns the electricity from the load like a light bulb, motor, etc. to the electric panel. Technically it is a current carrying ground wire and you can get a shock from it especially from a ballast from a fluorescent light.
The green or bare copper wire is the ground and is supposed to be non current carrying.
Older home and barns just have 2 wires, the oldest before ("romex" AKA type NM (nonmetalic)) is knob and tube.

Will a 117 volt led bulb work in a 110 volt circuit?
It should work okay.
How many hz is a 110 volt circuit?
Frequency is independent of voltage magnitude. It depends upon type AC or DC.
How many watts can a 20 amp breaker handle per hour?
2.3 kw per hour on a 110-120 volt circuit.
How can I install a 110 receptacle alongside a 220 receptacle using the 220 receptacle wires for power?
While you can physically do this it violates the Electrical Code. 110 Volt and 220 Volt receptacles are required by the Electrical Code to be on separate breakers for safety reasons, this would put them on the same 220 Volt breaker.
Can you use a neutral wire from a existing 110 volt 20 amp circuit to supply a neutral for a washer dryer combo that has only a 220 volt 30 amp 2 wire?
No !
How many wires are needed for 110 volt?
Hot, neutral and ground.
What happens when two wires are connected?
Wiring to the circuit breakers is 220 volts. The circuit breaker box has 2 110 Volt lines. If you connect two black lines together from one side nothing happens. If the these two black wires are from different circuit breakers you may have a safety issue by back feeding the electricity. If you connect 2 different 110 volt lines you will end up with a short. This ends up as a 220 volt short.
Will a 117 volt led bulb work in a 110 volt circuit?
It should work okay.
Can 110 volt apliance work on 220 volts circuit?
NO - that is dangerous.
Is there an adapter that will make a 110 volt refrigerator receptacle into a 220 volt?
No. You need to rewire the circuit from the electric panel.
How many hz is a 110 volt circuit?
Frequency is independent of voltage magnitude. It depends upon type AC or DC.
Can 110v circuit power 240v devices?
You need a step-up transformer, to go from 110 to 220-240 volts. Then a 110 volt supply can operate 240 volt equipment.
How many watts can a 20 amp breaker handle per hour?
2.3 kw per hour on a 110-120 volt circuit.
Can a 120 volt appliance run on a 110 volt circuit?
Yes. Circuits in a home are 120 volts but people tend to call them 110 volt circuits. The 120 volts you read on the appliance is the maximum voltage the appliance can handle. The actual voltage you will read at any outlet will range from 110 to 120 volts.
How can I install a 110 receptacle alongside a 220 receptacle using the 220 receptacle wires for power?
While you can physically do this it violates the Electrical Code. 110 Volt and 220 Volt receptacles are required by the Electrical Code to be on separate breakers for safety reasons, this would put them on the same 220 Volt breaker.
Will a 240 volt lamp work in a 110 volt supply if the supply fuse size were increased?
No. The 240V lamp will pop the circuit or fuse because the draw is higher than the supply.
Can you use a neutral wire from a existing 110 volt 20 amp circuit to supply a neutral for a washer dryer combo that has only a 220 volt 30 amp 2 wire?
No !
