Why is current direction always shown wrong?
becuase electrons are always motion in outer orbital
What action results in an ampere of current?
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)
Define non uniform motion?
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.
What are the similarities and differences between direct current and alternating current?
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.
Why conductors offer resistance?
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 .
How does the quantum mechanical model describes energies?
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
What describes motion of a car?
Acceleration describes the motion of a car. Acceleration is defined as an increase in the rate or speed of something.
How do electrons spin?
Electrons have an intrinsic property called "spin," which isn't the same as actual spinning motion. It is a quantum mechanical property that describes an electron's intrinsic angular momentum. Electrons can have a spin value of either +1/2 (spin-up) or -1/2 (spin-down).
What motion best describes the way a wave moves?
a sweeping motion
What best describes the motion on iron atoms in solid iron?
Kinetic energy best describes the motion of the particles in a piece of steel.
What is the word that describes an up and down motion?
The word that describes an up and down motion is vertical. Stairs are considered vertical, even though they are usually set at an angle. Horizontal would mean a side to side motion.
What particles in a substance are in motion?
The electrons can be in motion. These are present outside the nucleus.
What keeps electrons in motion?
The nucleus
Which term describes the describes the disorder of random molecular motion?
entropy
How do the Bohr model and the mechanical model of the atom differ in how they describe electrons?
the bohr model suggests that electrons follow orbits around the nucleus. Quantum mechanics describes electrons differently and gives them different properties. It tells us where an electron is most likely to be found but no defined path of motion around the nucleus
What is the process of harmonic motion losing amplitude over time?
Destructive Interference
Since electrons exhibit wavelike repeated motion?
Electrons are subatomic particles. Since electrons exhibit wavelike repeated motion, they tend to follow the same path around an atom.
