Photo electrons. So current due to these photo electrons is named as photo electric current.
The ability of light to cause electron movement and electric current is known as the photoelectric effect. When photons of light strike a material, they can transfer their energy to electrons, causing them to be ejected from the material, which can then result in the generation of an electric current.
The current rises as does the intensity of light detected. The more light the greater the intensity, and the greater the current. The answer to the question is that photoelectric current displayed on a graph is shown as a slope that varies with the intensity of light. Someimes it can go up, sometimes it can go down.The ultimate answer is that the photoelectric effect is unreliable, but it is improving!
Yes, in the photoelectric effect, when light shines on certain substances, electrons are ejected from the material, creating an electric current. This effect occurs when photons (light particles) transfer enough energy to electrons in the material to overcome the binding energy holding them in place.
Urey and Miller used an electric current in their experiment to simulate the effects of lightning in the early Earth's atmosphere. They wanted to see if the combination of gases found in the atmosphere at that time could produce organic compounds like amino acids, which are the building blocks of life.
Switching to a brighter light source. Switch to a light source with a higher intensity.
Increasing the intensity of light incident on a photoelectric material increases the number of photons hitting the material, which in turn increases the rate at which electrons are ejected from the material (photoelectric current). Consequently, higher light intensity leads to a higher photoelectric current.
The element commonly used in photoelectric cells is silicon. Silicon is a semiconductor material that can absorb photons of light and generate an electric current.
Yes, in the photoelectric effect, electric current is produced when light shines on certain substances known as photosensitive materials. This occurs when photons (particles of light) strike the material's surface and transfer their energy to electrons, causing them to be ejected and generate an electric current.

Solar energy uses the photoelectric effect to convert light energy into electrical energy. When sunlight shines on a solar panel, the photoelectric effect causes electrons to be released, creating an electric current.

Ionization in a photoelectric smoke detector helps detect smoke particles by creating an electric current when smoke enters the detector chamber. This current triggers the alarm, alerting people to the presence of smoke and potential fire.
The photoelectric current depends on the intensity of light shining on the surface, the frequency of the light, the type of material the surface is made of, and the energy of the individual photons. Increasing any of these factors can result in a higher photoelectric current.
I think that you talk about the usage of galvanometer in photoelectric emission experiment. Right? The main purpose of using a galvanometer is to know about whether current flows or not and also the direction in which current flows. Moreover current flows right from anode to cathode and electrons do flow from cathode to anode within the discharge tube.
A photoelectric cell or solar cell needs sunlight to produce electricity. When sunlight strikes the cell, it excites electrons in the material of the cell, generating an electric current through the cell.
he is awesome
