Q:Quick question about electrical wires.?
What it sounds like is happening there is that the switch box is the main feed for the room. You have a set from the panel, a set for the light fixture, and a set that are downstream, such as for an outlet. You need to determine which set is which. Then cut a piece of black wire and a bare copper about 8 long. This is how the connections are made: TURN THE POWER OFF. Then connect all of the whites together with a wire nut. Connect the new bare copper to the other grounds with another wire nut. Then connect the black from the panel, the downstream black, and the short black together with another wire nut. The black to the light fixture and the black pigtail (short wire) connect to the 2 brass terminals on the switch. The bare copper pigtail goes on the green screw on the switch. Reinstall the switch in the box, turn the power on, and check your work. If the light stays on at all times, but the outlets only work when the switch is on, those 2 wires are reversed. Turn the power off, switch the wires, and you should be good to go. Hope this helps.
Q:How do I fix my outlet wire ?
using a wire nut just get the same size wire cut it about 4 inches long and make whats called a pig tail use the wire nut to connect the new wire to the short one its most likley a 14/2 wire if its on a 15 amp breaker if its on a 20/amp you should use a 12/2 wire
Q:question about tension in wires?
The length of the wire is inconsequential unless you're calculating stretch. The tensile force in the upper wire is simply: Fu = 6 + 10 = 16 kg The tensile force in the lower wire is simply: Fl = 10 kg If you want tensile stress, then you need the wire's cross-sectional area.
Q:Remote Wire?
The remote wire is the blue/white wire. The power antenna wire(blue) only has current when the tuner is being used therefore your amp would only work with the radio and nothing else.
Q:True or False? Three Phase Wiring?
False! If you had 6 120v circuits each circuit has 1 phase, 1 neutral conductor and 1 ground conductor for a total of 3 wires per circuit. 6 circuits times 3 conductors equals 18 wires. You don't use the same neutral conductor for different phases but you can if they are the same phase provided you don't go over the maximum allowed current rating for that wire and insulation.
Q:Harmonics of a wire?
Kia ora In order to answer this question, we first need to ascertain the speed of a wave in this wire. The speed of a wave on a wire depends upon the tension 'T' and the linear density (mass per unit length) 'μ' of the wire. v=√(T/μ) T=600 N The linear density of your wire is 5.00E-4 kg/0.95=5.263E-4 kg/m. So for this wire, v=√(600/5.263E-4) =1068 m/s Now we have the speed, we need to find the wavelengths that correspond to the harmonics we are interested in. The wire is fixed at both ends. Nodes occur at fixed ends. Therefore the first harmonic will occur when there is a node at each end and the longest possible wavelength that satisfies this condition is λ=2L (you get half a wavelength on the wire). So λ=2*0.95=λ=1.90m. If v=1068m/s and λ=1.90 then by the wave equation v=fλ f=v/λ=1068/1.90=562.1 Hz. So that is the first harmonic. The second harmonic has twice the frequency of the first; the third harmonic has three times the frequency of the first. The second harmonic will therefore occur at 562.1*2=1124 Hz and the third at 562.1*3=1686 Hz. Because your data was given to 3sf you need to round your answer to 3sf: 1st harmonic: 562 Hz 2nd harmonic: 1120 Hz 3rd harmonic: 1680 Hz
Q:wind generator wiring?
You need some ring contacts and brushes that will be touching those rings that will be spinning while the generator does to complete a circuit without twisting wires. Make sure you get the right size rings and wire for the amount of current
Q:Is it because of my wire?
Shortening your speaker wire will not cause this problem. In fact, shortening your speaker wires should give you less static since there is less resistance. Most than likely, it's not your speakers causing the static sound, but your amplifier or receiver. You may be looking for a new one soon.
Q:Wire an outlet???
i am an electrician and i cant believe that the white wire is hot. i would double check it to make sure. use a volt meter.take the negative probe and touch the box if it is a metal box. if romex cable was used just touch the bare ground wire. touch the white and black wires one at a time with the positive probe to see wich is hot. every outlet has 4 sdrew terminals 2 brass and 2 silver. the hot wire always gets hooked to the brass terminals. i would check the circuit breaker box to see how the wires are hooked up. the black wires should be hooked up to the circuit breakers the white wires should be hooked up to the nuetral bar. if not you're house was wired backwards.
Q:Physics Help! resistivity of a wire!!!?
Voltage (Volts) = Current (Amps) times Resistance (Ohms) or V=IxR = R = V/I = 13/0.37 = 35.14 Ohms Resistance = Resistivity * Length/Area The longer the wire is, the more resistance it has. The larger the crossectional area of the wire (pi times radius^2), the less resistance it has Longer wires have more resistance, thicker wires have less 35.14 = Resistivity * 3.1/pi*0.0042^2 Resistivity = 35.14*pi*0.0042^2/3.1 = 6.281 x 10^-4
