Q: Three parallel wires are each carrying a 4A current. ; wire A) is 6 mm from wire B) which is 3mm from wire C); The current in wires B and C are out of the paper, while A is into the paper. What is the magnitude and direction of the magnetic field halfway between wires A and B?I have tried using Biot-Savart Law but keep getting it wrong can someone please help? I also have an equation for two parallel wires but how do I relate it to two?: You can use the Biot-Savart Law, but it is confusing and kind of a waste of your time and space. For straight wires, someone ALREADY worked out the Biot-Savart Law. See the following link for the result: hyperphysics.phy-astr.gsu.edu/Hba... The formula of interest for us is B = mu0*I/(2*Pi*r) where mu0 is magnetic permeability of free space, I is current, and r is distance from the wire carrying the current. B is the magnetic field due to that PARTICULAR wire. To deal with three wires, use a superposition principle and stack magnetic fields on top of each other. Do be aware of direction: remember the right hand rule. RH rule for magnetic fields in vicinity of wires: point thumb in direction of current, curl fingers to show the magnetic field circulation direction. Use this sign convention: + B is up along page, -B is down along page For Wire A: point of interest is r = d_ab/2 or 0.003 m to the right of wire A Point thumb in to the paper and the finger curl indicates that B_A is downward B_A = -mu0*I_A/(pi*d_ab) For Wire B: point of interest is r = d_ab/2 or 0.003 m to the left of wire B Point thumb out of the paper and the finger curl indicates that B_B is downward B_B = -mu0*I_B/(pi*d_ab) For wire C: point of interest is r = d_ab/2 + d_bc or 0.006 m to the left of wire C Point thumb out of the paper and the finger curl indicates that B_C is downward B_C = -mu0*I_C/(2*pi*(d_ab/2 + d_bc)) Add up: Bnet = B_A + B_B + B_C Bnet = -mu0*I_A/(pi*d_ab) - mu0*I_B/(pi*d_ab) - mu0*I_C/(2*pi*(d_ab/2 + d_bc)) Simplify: Bnet = -mu0/pi*(I_A/d_ab + I_B/d_ab + I_C/(d_ab + 2*d_bc)) data: mu0:=4*Pi*10^(-7) Tesla-m/A; I_A:=4 A; I_B:=4 A; I_C:=4 A; d_ab:=0.006 m;d_bc:=0.003 m; Result: Bnet = -6.667 milliTeslas negative sign indicates downward direction.

Q: Wire diagram: Hello there George, It has become common over the past few years that non-residential boilers are wired with EPO (emergency, power off) switches just outside each door to the boiler room. This is similar to having fire alarm pull boxes by the exits. I do not know of any jurisdiction that requires it for a residence. On occassion I've seen the 24 volt circuit for the thermostat being switched, which is a bit sketchy. Normally the 120 volt circuit for the controller is switched. The switches used are of the pushbutton type.

Q: 4.A uniform semicircular sign 1.00 m in diameter and a weight of 325 N is supported by two wires. What is the tension in each of wires supporting the sign?: Assuming the wires are vertical, connected evenly to the sign, and that nothing else is supporting the sign, then each wire carries half of the weight. T = 325 / 2 = 162.5N

Q: What good would it do to change my spark plugs and wires would it be a good idea for a 86 year of a car they've never been changed before I was wondering would it help the car out thanks for the help: sure it would help it. it would give it more power, easier starting and easier on gas

Q: I am replacing a regular light switch with a more fashionable looking design. When I took out the old light switch there was a red and a black wire attached. I am used to white and black. Which wire is considered the white wire when I am wiring this switch?: Switches don't require a neutral (white wire) One of these wires is hot..the other feeds the fixture. Attach to the terminals of the switch. More than likely if you look into the box you will see the white wires maretted together for continuity return

Q: What's the factors affecting resistance of a wire? and why? thank you!: i) Cross-sectional area of the wire. Reistance is inversely proportional to the area of cross-section of the wire. More the cross-sectional area, easier it is for the electrons and hence charge to flow and hence more current and less resistance. ii) Length of the wire. Resistance is directly proportional to the length of the wire. More the length of the wire, longer is the distance to be covered by the electrons and hence charge thereby reducing current and increasing resistance. iii) Temperature. Higher temperature results in higher resistance. Higher the temperature, faster will be the oscillations of the ions in the conductor and the moving electrons will have to undergo more number of collisions per unit length of the wire, thereby reducing time between successive collisions and reducing drift velocity of the electrons which results in less current and higher resistance iv) Material of the conductor Some materials like metals are better conductors of electricity and offer less resistance to the flow of current. Non-metals have poor conductivity. Conductivity of charge in metals is mainly due to the free electrons in the outer orbits of metals.

Q: I just bought a remote starter/keyless entry/alarm system, i'm looking to install it myself... I'm just wondering what gauge wire that most cars use.I'm assuming power wires are lower gauge then others, Could I use 16 gauge for power lines or would i need something larger?Thanks in advanced.: Why do you need to wire the stereo to the battery? Only thing you should have to wire directly to the battery is an amp. If you are wiring the amp to the battery I would say use a 4 gauge. Now, this depends on the rms of watts going to the amp, but 4 gauge is always a safe bet and give you room for growth in the future if you want to upgrade.

Q: hey could anyone tell me from the stock am radio in my nissan 720 what wires are the constant (memory) power and the accessory (ignition) wire so i can attach these to my new radio: Nissan Radio Wiring

Q: How do I wire with reg 5 wire T-Stat Installing a 2 ton Goodman A/C cond unit to a old Carrier Heat pump AHU with emergency heat strip.: If you're wiring a thermostat to control a conventional condensing unit (non-heat pump) and a heat pump air handler, it is no different than wiring a conventional condensing unit and a standard non-heat pump air handler. Yellow (or Blue) - Y White - W Green - G Red - R The only question would be the remaining wire. Was it used to energize the reversing valve (O terminal on heat pump thermostat)? If so, you could take that wire and tie it into the C (common) wire/terminal at the air handler. That is, if your thermostat has a C terminal. If not, the wire would not be used. I'd suggest making sure those are the wire colors being used by checking them at the air handler first.

Q: im hooking a amp up and i need to run my remote wire to my ignition wire: I have wired up alot of amps and the remote wire on the amp should be connected to the power antenna/amp turn on wire on the stereo head unit. This allows the amp to only turn on when the stereo is on. If you are connecting an amp to a factory stereo,I see why you would need to find an ignition wire. You need to probe the fuse panel with a 12 volt test light to find a circuit that only comes on with the key. Usually there is a spare accessory fuse location just for this. Buy a fuse tap or specialty fuse from a auto parts store to connect your remote wire to. There is very little current draw to turn on the amp,so almost any circuit on the fuse panel will work if it is only on with the key.
