The era of modern physics is one of completely unexpected and inexplicable discoveries, however.

#LIGHT INTENSITY EQUATION CIRCUIT FREE#

All forms of electromagnetic radiation transport energy and it is quite easy to imagine this energy being used to push tiny particles of negative charge free from the surface of a metal where they are not all that strongly confined in the first place. While this is interesting, it is hardly amazing. Thomson showed that this increased sensitivity was the result of light pushing on electrons - a particle that he discovered in 1897. Hertz found that he could increase the sensitivity of his spark gap device by illuminating it with visible or ultraviolet light. The air gap would often have to be smaller than a millimeter for a the receiver to reliably reproduce the spark of the transmitter.

Compared to later radio devices, the spark gap generator was notoriously difficult to work with. In these experiments, sparks generated between two small metal spheres in a transmitter induce sparks that jump between between two different metal spheres in a receiver. The photoelectric effect was first observed in 1887 by Heinrich Hertz during experiments with a spark gap generator (the earliest device that could be called a radio). All electrons are identical to one another in mass, charge, spin, and magnetic moment. This process is called the photoelectric effect (or photoelectric emission or photoemission), a material that can exhibit this phenomenon is said to be photoemissive, and the ejected electrons are called photoelectrons but there is nothing that would distinguish them from other electrons. Please leave a comment below if you have any questions.Under the right circumstances light can be used to push electrons, freeing them from the surface of a solid. May I recommend you print this note and check things off as you have master the topics.

Know that it will take some time for the material to sink in. As the inductor is 'turned off' it will act as a constant current source and do whatever is necessary to maintain the same current before and after the transition.Ĥ) Please search 'transistor characteristic curves.' Here you will find that a transistor appears to operate as an acceptable constant current source. Such a device would demand infinite current (again, not possible in this universe).ģ) Please search 'inductor kickback.' Here you will find than an inductor acts as a constant current source for a limited amount of time. Note that there is no such thing as a perfect constant voltage source.

To make one you would need a device that could produce an infinite voltage (not possible).Ģ) Please search 'Thevenin Norton Equivalent.' Here you will find that a voltage source with series resistance can be modeled as a current source with parallel resistor. To my knowledge there are no perfect constant current sources. It will take on whatever voltage is necessary to do so including both positive and negative voltages. I'll give you a few examples to consider:ġ) The current source is a mathematical construct that maintains a constant current. The current source is a different animal. With more current and a fixed voltage there will be more power. As you stated as the resistance is decreased more current flows. Examples include a battery or wall outlet. In my opinion the voltage source is relatively straightforward.
