WebSep 16, 2024 · For the photocurrent is proportional to the no. of electrons coming out of the metal in unit time, and this no. of electron depends solely on the intensity, ie. the number of photons per unit area per unit time, and not on the energy of the photons, ie. the frequency. This is what I am taught. An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume. The moving particles are called charge carriers, which may be one of several … See more The conventional symbol for current is I, which originates from the French phrase intensité du courant, (current intensity). Current intensity is often referred to simply as current. The I symbol was used by André-Marie Ampère, … See more Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that … See more Natural observable examples of electric current include lightning, static electric discharge, and the solar wind, the source of the polar auroras. Man-made … See more Joule heating, also known as ohmic heating and resistive heating, is the process of power dissipation by which the passage of an electric current through a conductor increases … See more The conventional direction of current, also known as conventional current, is arbitrarily defined as the direction in which positive charges flow. In a conductive material, the moving charged particles that constitute the electric current are called charge carriers. … See more In alternating current (AC) systems, the movement of electric charge periodically reverses direction. AC is the form of electric power most commonly delivered to businesses and residences. The usual waveform of an AC power circuit is a sine wave, … See more Current can be measured using an ammeter. Electric current can be directly measured with a galvanometer, but this method involves breaking the See more

WebKey terms. A field models what an object would experience related to a force at a given point in space. A magnetic field is a field explaining the magnetic influence on an object in space. A electric field is a field defined by the magnitude of the electric force at any given point in space. Current is the rate of charge moving past a region.
WebJul 29, 2024 · Hi all, I am really confused about the relationship among these three properties and I cannot find an answer satisfying enough.. If frequency of incident light increases but intensity remains the same, the photocurrent will decrease. Does this mean that the new curve on the current vs. voltage... WebFeb 9, 2024 · What is the relation between intensity and electric field? The energy carried by any wave is proportional to its amplitude squared. For electromagnetic waves, this …
WebEinstein concluded that increasing intensity increases current because more photons would be released and consequently more electrons and more current. Thus, when we talk about photoemission and Compton effect, we consider light as particle; but when we talk about diffraction, interference and polarization, we consider light as wave. WebNov 11, 2004 · 5614. relationship = more current = more light intensity (until a limit which is quite high, far higher than a normal household light, but super-super-hyper-mega …
WebCurrent density or electric current density is very much related to electromagnetism. It is defined as the amount of electric current flowing through a unit value of the cross-sectional area. In case of a steady current that is flowing through a conductor, the same current flows through all the cross-sections of the conductor.
