Q:I just read an article about a man who was electrocuted by a live overhead wire while trimming a tree. Horrible. My question is I see squirrels running on all the overhead wires. How do they not get electrocuted?

You have to have a complete circuit. A man trimming trees may touch two wires at the same time or may touch one and the other wire is grounded causing the ground to act as the second wire. You cannot get electrocuted by touching just one wire. Technically, since one wire is grounded and we are on the ground we are touching one wire continuously. Also the squirl may be on a low voltage telephone wire or an insulated wire. If it's a bare wire and he doesn't jump onto the wire but rather reaches out from a tree and touches both at the same time he'll get shocked too.

Q:The resistivity of a 18.0 m long wire is 3.76E-8 Ω.m and its cross sectional area is 6.52E-6 m2. If the wire carries a current of 1.44 A, what is the voltage across the wire?

R = ( rho x l)/A Where: R is the resistance, rho the resistivity, l the length and A the area Resiatance of wire = (3.76 x 10^-8 x 18)/6.52 x 10^-6 R = 0.1038 Ohms Voltage across wire = current through wire x resistance of wire V = I x R V = 1.44 x 0.1038 V = 0.14947 V = 0.15 Volts

Q:I am changing an outside light with a inside wall switch there is 2 cables going to the outside box. ( 3 wires -white w/red line wire and black wire and green ground wire ) other cable 3 wires is white wire and black wire and green ground wire.On the inside switch is 3 wires white wire a black wire a green ground wire.for some reason it is not working, can any one tell me how to wire and or test for power. thank you

I changed my outside light and sounds like the wires were similar to yours. Make sure you have the power turned off. And, connect and twist the wires (same colored) together, and use the caps, and connect the green ground wire and turn on the power to test it again. Might want someone near the power switch and someone to watch the light to make sure sparks don't fly. And, make sure you have a bulb that works in there. Otherwise might want to contact someone knowledgeable (family member/electrician) with help.

Q:Does anyone know where i can buy them? I need new ones because my crazy cat chewed up two of the wires lol =#92;

Buy some speaker wire and electrician's tape and splice new wire in the area where the old wire is chewed. Make sure you don't cross positive with negative. This way, you don't have to worry about getting the right connections, and it will be inexpensive.

Q:@topicAnd does the size of the wire matter in electrical consumption?

The size of the wire that matters in electrical consumption.

Q:Phone wire outside was old is anybody done that, do it your self put a new wire on?, Just curious to know..

Outside wire would feed back to the telephone central office and will either be aerial wire, connected to poles, or buried. Either way it is not feasible for someone other than the telephone company to replace.

Q:The wire from the cicuit breaker

I agree with the #10 unless the dryer is like 100 feet from the electrical box(very unlikely).

Q:I removed a dishwasher and now the wires are exposed. I turned off the circuit to that outlet. I am planning on waiting a while to replace the dishwasher. I want to turn the circuit back on so I can use the other outlets, but don't want to leave the wires exposed. Any ideas?

Are they in an electrical box,or just hanging there? Either way, you need to twist them (individually) screw the proper sized wire nut on to them, then wrap some electrical tape around them. If they have a box, you can just put a cover on it. If they are just dangling out of the wall,( very unusual,but you never know) Just put a plain cover over them, after wrapping them. After they have been wrapped separately, it will be safe to turn the breaker back on. Use a electrical tester before touching any electrical wiring,even after you think you have turned the breaker off. I almost killed myself thinking the breaker I shut off lead to the particular wire I was working on. Come to find out, a switch to a light, and an outlet not more then a foot away from that ,were pigtailed on to separate circuits. Don't ever guess, or assume nothing when working around electricity. Byee

Q:whats a good brand for 0 gauge wire to get? im looking for a good brand that has 100% OFC wire, i would get knukonceptz, but their wires are copper coated aluminum which isnt as good.

Q:electrical wire prices

Doh!! The reason the prices of wire follow the prices of oil, the outer jacket of Wire is Plastic an oil based product, Thus the reason oil goes up so does the prices of wire.
