Thermal noise
becuase electrons are always motion in outer orbital
MOTION OF A CHARGE (1C) IN A TIME OF 1S RESULTS THE AN AMPERE OF CURRENT TO FLOW..... on a broad way I= q/t q=ne so I= ne/t so put e = charge of electron, t=1s I= 1A then u will get how many electrons are flowing to constitute the current of 1A (e= 1.66 X 10-19 (-19 is in rays to power of 10)
Think of uniform as everything moving together. For example, in uniform circular motion describes the motion of a body traversing a circular path at constant speed. The distance of the body from the axis of rotation remains constant at all times. If the motion was non-uniform the distance of the body from the axis of rotation would vary.
Both alternating current (AC) and direct current (DC) describe the nature of the current in terms of its direction. DC describes when the flow of electric charge goes in a constant direction whereas AC describes when the flow of electric charge constantly reverses; in other words, the electrodes of the power source constantly switch between positive and negative.
Yes , all conductors have some amount of resistance although it varies depending on the material that is conducting the electricity . Copper has a very low resistance, and aluminum has a slightly higher ( but still quite low ) resistance . This is why they are used as electrical conductors. Conductor resistance results in voltage drop over the conductor and power loss, manifested as heating of the conductor . Therefore , you want as low a conductor loss as is reasonably practical . The reason of resistance is that, no electron has a linear motion when an electric field is applied to it . e- move in random due to apparent collision with other e -' s. This motion is termed to as Brownian motion . The random movement however interrupts with the electric field and creates resistance sue to a negetive field generated .
According to the modern theory of quantum mechanics the electrons have a vibrating wave character and hence uncertain positions.Sometimes,they are close to the nucleus and sometimes away from it.Thus we can say that the paths of motion of electrons around the nucleus are not definite
Acceleration describes the motion of a car. Acceleration is defined as an increase in the rate or speed of something.
The electrons can be in motion. These are present outside the nucleus.
The nucleus

The type of motion that describes the horizontal component of a projectile is horizontal projectile motion. It is influenced by the downward force of gravity.
a sweeping motion
Destructive Interference
Kinetic energy best describes the motion of the particles in a piece of steel.
In metals electrons are in a permanent motion.
Electrons revolve around the nucleus of atoms in orbits.
