Any conductor has resistance. Maybe not much, but there's always some.
Any resistance dissipates power, at the rate of I2R. (I = current through it, R = its resistance.)
That's how you build toasters.
If an electrical current passes through a conductor, there is an induced voltage (because no conductor has perfectly zero ohms), resulting in power dissipation, and there is a magnetic field, which can interact with other conductors in the vicinity of the first.
Various flammable gasses, flammable liquids, and combustible dusts can ALL explode when mixed with sufficent air, and an electrical spark creates enough heat to ignite the mixture. Examples would include hydrogen, propane, gasoline, alcohol, powdered sugar and flour.
The adjustment factor for a raceway or cable with 7-9 current-carrying conductors is typically 70%. This means that the ampacity of each conductor must be reduced to 70% of its rated value to prevent overheating and ensure safe operation. This adjustment is necessary to account for the increased heat generated when multiple conductors are bundled together. Always refer to the National Electrical Code (NEC) for the most accurate and applicable guidelines.
The heat observed in a circuit is the result of electrical resistance.Under normal circumstances, every electrical circuit has a certain amount of resistance to the flow of electricity. Electronflow opposed by the physical nature of the conductor. This is the fundamental nature of electrical resistance. Whenever this happens, the energy of those electrons is absorbed by the conductor (as opposed to flowing through) which then emitts this captured energy as heat. The higher a conductor's resistance, the more electrical energy is converted to heat by it.
you need more information my way. you use 2 formula v=ir and p=i*i*r. i=current r=resistance v=voltage and p=power (heat given out)
resistance will be high
-- heat (if it isn't a superconductor) -- a magnetic field in the space around the wire
Bundled conductors have a higher current carrying capacity compared to a single conductor of the same total cross-sectional area, due to improved heat dissipation. This is because the proximity of the conductors allows for more efficient cooling and reduces the overall resistance.
The power dissipated by a resistance 'R' carrying a current 'I' is [ I2R ]. The power is dissipated as heat, and you can see from [ I2R ] that for a given current, it's directly proportional to 'R'.
You can have only one current carrying conductor in a conduit, but that conduit must have a slot to relieve the eddy currents that will be created by the transformer effect created by the conductor. It is better to run the neutral or opposite conductor along with the hot conductor together in the same conduit, or through the same penetration, so as to minimize this effect.
When current passes through a conductor, the electrons collide with atoms in the conductor, causing them to vibrate and generate heat. This is because the collisions lead to an increase in kinetic energy, which is released in the form of heat. The amount of heat produced is directly proportional to the resistance of the conductor and the square of the current passing through it, as described by Joule's Law.
The only limit on how much current the conductor can carry, regardless ofthe weather, is the amount of current that causes the conductor to melt.The current in such a conductor depends on the voltage between its ends,and on the resistance of the conductor. The resistance of the conductor issomewhat less when it's cold, so a given voltage would result in more current.
Air is a good conductor of sound, and a poor conductor of heat and electric current.
The heat produced in the conductor will increase four times when the current is doubled, as heat produced is directly proportional to the square of the current according to Joule's Law.
Yes, it is a horrible conductor of energy.
Current flowing through any conductor encounters resistance in that conductor. This resistance produces heat. (Think of tires on a car after driving on the highway. Smooth trip, but a small amount of friction (resistance) is inevitable.
Yes, every conductor will heat up to some extent when electric current flows through it due to the resistance of the material. The amount of heat produced is determined by the material's resistance to the flow of electricity.
