- The photo-electric effect causes a current to pass between two plates that already have a voltaic potential difference.
- the photovoltaic effect causes a voltage to grow between two plates that don't already have one (or changes the applied voltage to something else). There is no current.
In photo electric effect,
- When light(photon) Strikes on the one plate,electron in outershell of atom is ejected by absorbing the light.And electron can move from its plate to other plate if energy of photon is satisfy the break force of surface into electron and potential energy of two plates.So current is generated.
In photo voltaic effect,
- When light(photon) Strikes on the one plate, electron in outershell of atom is go up to new energy level by absorbing the light. So no charge carriers move.Therefore no current.

What is hall effect hall voltage?
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879
Difference between variation order and site instruction?
Variation Order is a Site Instruction which have effect on Time, Quality and Cost. But if we entitled it as Site Instruction only, usually it does not have effect on Time, Quality and Cost.
Is current present in everything of this physical universe?
No and (maybe) Yes.No. Current is the movement of electric charge from one point to another under the influence of an electric potential difference. You can have charge without current.(Maybe) Yes. You can also argue that charge is constantly moving at the atomic level as the electrons move between their various quantum states, but you can also (maybe) argue that this is not in response to an electric potential difference. You can also argue that, once you back out even a little bit and broaden your point of view, the net effect of that movement is zero.The normal understanding of current is a daisy-chaining of electrons jumping from atom to atom at the valence shell level under the influence of a much more global electric potential.

What are the differences between the photoelectric effect and Compton scattering in terms of their interactions with photons and electrons?
The photoelectric effect involves the ejection of electrons from a material when it absorbs photons, while Compton scattering is the process where photons collide with electrons, causing them to change direction and lose energy. The key difference is that in the photoelectric effect, electrons are ejected from the material, while in Compton scattering, electrons remain within the material but change their direction and energy.
When was The Compton Effect created?
The Compton Effect, also known as Compton scattering, was discovered by physicist Arthur Compton in 1923 and was confirmed experimentally in the following years. This effect describes the increase in wavelength of X-rays when they collide with electrons.
What is the difference between Compton scattering and the photoelectric effect in terms of their interactions with photons?
Compton scattering involves the collision of a photon with an electron, resulting in the photon losing energy and changing direction. The photoelectric effect, on the other hand, involves the absorption of a photon by an electron, causing the electron to be ejected from the material. In summary, Compton scattering involves the photon changing direction and losing energy, while the photoelectric effect involves the absorption of the photon by an electron.
What are the differences between Compton scattering and the photoelectric effect in terms of their interactions with matter?
Compton scattering and the photoelectric effect are both ways that X-rays interact with matter. The main difference is that in Compton scattering, X-rays collide with electrons in the material and lose energy, causing them to change direction. In the photoelectric effect, X-rays are absorbed by electrons in the material, causing them to be ejected from their atoms. This results in the X-rays losing all of their energy.
What did Arthur Compton invent?
Arthur Compton discovered the Compton effect, which demonstrates the particle-like behavior of light. This discovery provided evidence for the concept of photons and helped pave the way for the development of quantum mechanics.

What are the differences between the Compton effect and the photoelectric effect in terms of their interactions with matter?
The Compton effect involves the scattering of X-rays by electrons, resulting in a change in wavelength and energy of the X-rays. The photoelectric effect, on the other hand, involves the ejection of electrons from a material when it is exposed to light, without any change in wavelength. In terms of interactions with matter, the Compton effect involves interactions with free electrons, while the photoelectric effect involves interactions with bound electrons in atoms.
What are the differences between the photoelectric effect and the Compton effect in terms of their interactions with matter and the behavior of photons?
The photoelectric effect involves the ejection of electrons from a material when photons of sufficient energy are absorbed, while the Compton effect involves the scattering of photons by free electrons in a material, resulting in a change in the photon's wavelength. In the photoelectric effect, photons interact with electrons in the material, leading to the ejection of electrons, while in the Compton effect, photons collide with free electrons, causing them to scatter and change direction.
What is the greatest change in wavelength in compton effect?
The greatest change in wavelength in the Compton effect occurs when the incident photon scatters off an electron at a 180-degree angle. In this scenario, the change in wavelength is at its maximum value, known as the Compton shift.
What is the difference between dynamic torque and static torque ratings?
One difference between dynamic torque and static torque is the level of difficulty to measure. Static torque is each to measure, while dynamic torque is not. This is because it requires a transfer of an electric or magnetic effect.
