What is the effect on the drift velocity of free electrons by decreasing the length and the temperature of wire?
As we know , resistance(R) is directly proportional to length(L) of conductor and resistence(R) is inversely proportional to current (I) and I=nAqv (v is drift velocity) So , if we decrease the length of the conductor , resistance of the conductor will decrease and current(I) will increase and drift velocity of free electrons will increase . And as we know resistance and temperature have direct relation so , by decreasing the temperature resistence will decrease and current will increase . So drift velocity will increase .
Does a neutral wire carry current in an electrical circuit?
Yes, a neutral wire carries current in an electrical circuit.
What small piece of wire melts of it gets to hit due to electricity?
A small piece of wire will melt when it reaches its melting point due to the heat generated by the flow of electricity. This phenomenon is known as electrical overload or short circuit, where the wire cannot handle the excessive current and overheats to the point of melting.
What is the voltage of the neutral wire in an electrical circuit?
The voltage of the neutral wire in an electrical circuit is typically close to zero volts.
What voltage does a neutral wire have in an electrical circuit?
In an electrical circuit, the neutral wire typically has a voltage of around 0 volts.

The magnitude of momentum of electrons in a straight wire of copper of length 1 meter carrying a current of 16 ampere will be?
I=charge/second 16A=16C/s 16C=16*(6.25*10^18 electrons) 16C=100*10^18 electrons mass of 1 electron=9.1*10^-31 kg mass of 100*10^18 electrons=91*10^-12 kg/s length 0f wire=1m momentum=91*10^-12 kg/s * 1m 91*10^-12 kgm/s
What is drift velocity?
In a current-carrying circuit, a charged particle is accelerated by an electric field. It also undergoes frequent collisions with the stationary ions of the wire material. These two effects result in the very slow net motion (drift) of moving charged particles in the direction of the electric force. The drift velocity describes this motion. Average drift speed for electrons is on the order of 10-4 m/s (Young and Freedman, University Physics).
Which wire is the common wire in a typical electrical circuit?
The common wire in a typical electrical circuit is the neutral wire.
In a copper wire of cross section 1 square centimeter in which current of 200A flows in copper there are 8.510to the power of 28 freeelectron per cubic meter .calculate the drift velocity?
The drift velocity is found from the formula; V = I/nqA Where n = 8.5 x10^28 1/mmm (number density of free electrons) q = 1.6 x 10^-19 C (electron charge) I = 200 A (current) A = 1 x10^-4 mm (cross sectional area in square meters) V = drift velocity in meters/sec My calculator is dead so you'll have to do the calculations. Ok, calculator fixed. I get .000147 m/s = 14.7 x 10^-5 m/s
What do you call an electrical wire that is not insulated or covered?
The electrical terminology of a wire with no insulation on it is a bare wire.
How can I extend the length of an electrical wire using an electrical wire extender?
To extend the length of an electrical wire, you can use an electrical wire extender. This device allows you to connect two wires together securely, effectively increasing the overall length of the wire.
