Current and intensity relation
WebAnswer (1 of 3): Unfortunately there is no relationship in general, unless you’re intending to ask something much more specific. Light bulbs are sold by both the electrical power … WebIts definition is the following: The effective AC current is the current value such that the average power transfer would be the same on an DC current. So, power is therefore calculated: $$ P(t) = V(t)I(t) $$ For AC circuits where voltage and intensity varies with time, we have a varying power: $$ P(t) = V_0 I_0\cos(\omega t)\cos(\omega t ...

WebThe variations in photoelectric current which is produced as a result of photoelectric effect are caused by the intensity of light. Various studies have been conducted to explain the relation between variations of photoelectric current and intensity of light. In physics, the intensity or flux of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy. In the SI system, it has units watts per square metre (W/m ), or kg⋅s in base units. Intensity is used most frequently with waves such as acoustic waves (sound) or electromagnetic waves such as light or radio waves, in which case the average power transfer over one period of the wave is used. Inten…
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. WebVideo transcript. in this video we're gonna change the brightness and the color of the light or the intensity and the frequency of the light and see how that affects the graph of the photoelectric effect and the reason i have two graphs is because we'll do two cases now before we start let's quickly recap what this graph was all about on the ...
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 … WebAn electric circuit is capable of transferring power. Current is the rate of flow of charge, and voltage measures the energy transferred per unit of charge. We can insert these …
WebMay 18, 2024 · Lux also determines the magnitude of light intensity travelling over distances. A light that is configured for high lux output will travel farther but will have a smaller footprint of light , and a low lux level will be configured to travel shorter distances but have a larger footprint. 2 What is lumen? Lumen is the unit of the light current.
