What is electrical raceways?
an exposed conduit used for carrying electrical wires/cables
An electric heater is stretched to increase its length by 25 percent what is the increase in resistance?
In this case, the resistance will increase in inverse proportion to the wires new diameter, and in direct proportion to the wires new length.
Why current carrying wires become hot?
Resistance. Need larger gage wire
How many wires are normally connected to a double-filament light bulb?
5
What colour wires are live and ground in 96 mondeo?
Normally Red, Black, or Orange are hot and Green, or Possibly Brown are ground. To be sure, use a voltmeter, set for 12 volts D.C. and check each wire for current. Once you have isolated the wires carrying voltage. then switch to OHMS and check the other wires. Wires that are grounded will show a reading in OHMS.
What affects a wires electron flow?
The size of the conductor is in direct relation ship to its rating capacity of carrying a current. The larger the diameter of the conductor the larger the amperage rating capacity of the conductor.
Can two separate wires in parallel be used to increase the amperage capacity?
Yes they can but the electrical code states that the wires can only be 1/0 AWG and larger.
How do you increase the force exerted on a current carrying coil placed in a magnetic field?
Since the magnitude of force on a wire is I*L*B*sinθ, then you can increase the current, or increase the magnetic field, or adjust the angle so that it is per pendicular to the coil wires. You can increase the lenght (increase the number of turns).
What are the conductors in a circuit?
The wires carrying the power.
What is a current-carrying coil of wires with many loops?
solenoid
How does a pylon work?
A pylon holds up the wires carrying electricity. If there were no pylons the wires would drag onto the floor and if you were to tread on them you would get electrocuted by the wires.
Why dont phase and neutral exchange?
Phase wires are "hot" wires and are the current-carrying conductors. (These are the wires that will shock you if you touch them.). The neutral wire is basically there to carry the electricity back to the source. It is not normally considered current-carrying. If you switch these two wires, you might energize the metal of equipment, causing a dangerous shock hazard.

How does twisted pair look like?
That's just two wires twisted together, one carrying a signal and the other carrying the ground for that same signal.
How do you calculate current capacity of wire?
Current capacities of wires are normally not calculated. An electrician would normally refer to the allowable ampacities of wires in the (2011) NEC Table 310.15(B)(series) and 310.60(C)(series). Ampacity ratings are provided for a number of situations. If you want to use that math used to derive the figures for the tables... The current carrying capacity (in amps): I = 106 x D2/700 (cross-sectional area is 700 mils per amp)
