Never assume that any electric wire, no matter what color it has, is safe to touch.
First, you call a licensed electrician... The usual rule in the US at least is that black is the hot wire and white is the neutral wire. (If the wires are some color other than black and white, usually the darker wire is the hot wire.) However, you should never assume that whoever wired your house followed this rule; to be safe, you should always double check.
YES the white wire can shock. There are a few reasons why it might: 1) the white wire is actually connected to a switch. When the installer connects the white wire from the switch to the light, the National Electric Code requires the white wire to be "hot", and to be marked to indicate that it is hot. Sometimes this doesn't happen. The problem comes later when Joe homeowner replaces the light fixture. He sees the white wire with a black mark or maybe not, and connects the white wire to all of the other white wires. When the switch is turned on, the black wire that he placed on the other side of the switch connects to the white wire and trips the breaker. When Mr. Homeowner checks it out, touching the white wire gives him a shock. 2) The white wire returns the current to the source of the circuit. When the white wire is shared with two circuits, It returns the current from both circuits to the panel. When someone (even a professional) turns off only one of the circuit breakers to these circuits, the white wire still carries the current from the second LIVE circuit. If the person is replacing a receptacle withonly one of these circuit breakersoff, he or she could touch the white wire (called an open neutral) and get a shock from the returning current from the second circuit.
If you are referring to lamp cord type wire where both wires are brown then yes, connect the wire with the groves to the white neutral and the smooth wire to the black hot wire.
The neutral wire and power wire are never connected together.
In the US, if you only have a black wire (ungrounded or hot conductor) and a white wire (normally a grounded conductor or neutral) there is not a ground wire. Sometimes the white wire is used as a hot, so each wire would have to be identified. <<<< Electrical work should only be done by a qualified electrician.>>>>
Live wire is not to be touched. or Live wire touch not..haha
it safe i dont know will is safe you can dowlod lime wire it fee
In theory this should only ocure at the main junction box ... but if EVERYTHING is done right, then it is safe - but not in code.

You can use a wire tester to determine if a wire is live. You can also touch the positive wire on the ground wire, if the wire produces a spark it is live.

Perfectly safe.
Not if the wiring is correctly installed. The neutral should be at the same potential as the ground wire which is a zero or equal. To receive a shock your body needs to complete the circuit from a hot wire to ground or neutral. The above answer is not entirely correct. There are some instances where electricians use the white wire to carry load (or current). For proper electrical code though, the white wire should be identified as hot by wrapping a turn or two of black tape around the wire indicating as such. The most common way a white wire would carry power is a 12/2 cable running to a switch that controls lights or receptacles or etc. Power goes to the switch through the black wire and returns through the white wire to the load. The white wire should be wrapped with electrical tape to indicate this. A safe way to check if a white wire is hot is to check with a volt meter from the white wire to ground. A zero or close to zero voltage indicates the white is at ground potential and would not be hot.
I think it is safe
Yes, it safe to touch a extension cord while its plugged in.
The last fixture in a parallel circuit is wired the same as the first. In North America, all of the fixtures are wired black wire to black wire and white wire to white wire. The black wire being the "hot" wire and the white wire being the neutral wire.
If the standing wave is on the rope but not on the wire then you can touch it anywhere without disturbing the wire.
