voltage
If the solenoid wire is not insulated the number of turns will be reduced by the uninsulated wires touching and shorting out the turns.
By touching an uninsulated conductor which is under electrical tension.
Uninsulated wire does not have any outer protective covering, making it more susceptible to damage and electrical shock. Insulated wire, on the other hand, is covered with a material like rubber or plastic to protect the wire and prevent contact with electrical currents. This insulation provides safety and helps prevent short circuits.
Depends on what you are using it for:short point to point connection - yes, usually but be careful to avoid shortscoil winding - NO NO NO, the coil will be completely shortedgeneral wiring - NO NO NO, use hookup wire instead as the enamel is too fragile
Mainly because wires are insulated. In the case of being on an uninsulated wire the bird isn't grounded since both feet are on the wire.
A ground wire is a typically uninsulated copper wire. The intent is to connect the wire to an electrical appliance or fixture to provide electricity a path to ground in the event of a short, thus preventing electrocution.
Answer for USA, Canada and other countries using similar 60Hz household electricity supplies "Ground or "earth" wire has green insulation or is just bare uninsulated copper wire. Answer for Europe and other countries using similar 50Hz household electricity supplies "Earth" or "ground" wire has green/yellow striped insulation or is just bare uninsulated copper wire which should always have a green/yellow striped insulation sleeve put over it when it comes into any terminal boxes or plugs.
If your getting a shock by touching a wall than you have a bare wire touching the wall, call an electrition
If two uninsulated wires are close but not quite touching, the voltage may be sufficient to cause an electric current to bridge the gap through the air, thus creating sparks.
some how the tail light wire is touching the ajar wire
Because if the wire is "hot", that is, has electricity flowing through it, and you touch a bare wire, then YOU become the "ground" and complete the circuit. This will cause at the least a bad shock, and at the worst it will cause death. The "ground" wires are bare, but that is because they do not have electricity flowing through them unless something shorts out (ie a "hot" wire which is normally black or red in color touches a ground or neutral wire which is normally white. The "ground" wires are either bare or have a green coating.
Could have a short in your wire, a bare wire touching bare metal could cause it to ground out.
