Why ohm's law is not applicable in networks?
Ohm's Law: Volage = Current times Resistance Yes, voltage is proportional to current. That applies in simple circuits as well as to complex circuits such as electrical networks. Your statement that "voltage is inversely proportional to current in electrical circuits" is incorrect. Perhaps you are not considering some critical part of the statement, or you simply heard it wrong.
Why documentaries are useful?
They're not. They're all facts!! This is actually false because some are okay like why did the whale blow up in the street? And the plane crashes!
If a resistor converts electrical energy into heat are you wasting energy any time you use a resistor?
In one sense, using any resistor will "waste" energy. But consider that resistors serve a useful purpose, and the heat they generate is the price we pay for using them. Additionally, there are resistors that we use specifically to create heat for our use. The resistance in an electrical heating element on a range, in a hot water heater, or in a space heater are creating useful heat. We need the heat to cook food, heat water or warm a room. We generally make toast with resistance heating elements, to cite another application. In electronic equipments, resistors are used to "drop voltage" to make circuits work. We create heat when we use resistors to drop voltage, but it is a necessary part of circuit design and operation. In that light, we allow heat loss in order to gain the things the electronics do for us. When we watch TV or listen to music, we know that the electronic circuits in our equipment have some resistance that is generating heat. But that is part of the price we pay for having the use and benefit of the electronic equipment.
What are facts about Sweden mean?
It means some facts about Sweden. What else would it mean? Idiot.
What are some interesting facts about the Indian ocean?
sada
Are there electrical circuits in an electrical eel?
yes you can power some Christmas lights with an eel.
What checks should be done to an electrical measuring device before attempting to measure electrical resistance?
Some of the checks that can be done to an electrical device before checking electrical resistance include the proximity of other magnetic fields and other electrical circuits. Measure electrical resistance while at a safe distance from strong electrical circuits.
What are some circuits within an automobile?
Electrical circuits. Cooling Lubrication Hydraulic These are all circuits. The medium starts at one point, goes around a circuit and returns to the beginning, to start over.
What type of circuit allows some lights to burn and some to be off at the same time?
Parallel circuits.
What does the letter 'H' mean in electrical circuits?
It means generally "Hi"side of some electrical device (such as Hi -H- or Low -L- transformer side)
Why do you have to study about electrical circuits in electrical engineering?
Electrical circuits are just one aspect of electrical engineering, and a huge aspect at that. The core groupings within electrical engineering are electricity, electronics, electromagnetics, and photonics (of course there is a lot of overlap between these, as well as more sub-groupings). Electrical circuits mostly fall under the electronics category. To put it in perspective, studying EE without studying electronic circuits would be like studying chemistry without studying chemical reactions. Study or understand? if you do not understand it is best to study it. I am always studying new electrical circuit technology just to keep up with our changing world. Some say why and others say why not.
Can an insect cause an electrical short circit?
Yes, some insects can cause electrical short circuits. The insects can make nests inside fuse boxes and this can cause malfunctions.
Electrical wiring problems with some lighting circuits on a 1992 mercury grand marquis?
dash lights and tail lights cut out
Electrical engineering text books for 1st semester?
Some recommended textbooks for a first semester in electrical engineering might include "Fundamentals of Electric Circuits" by Charles K. Alexander and Matthew N.O. Sadiku, "Engineering Electromagnetics" by William H. Hayt Jr. and John A. Buck, and "Introduction to Electric Circuits" by Richard C. Dorf and James A. Svoboda. These textbooks cover essential topics in electrical circuits, electromagnetics, and basic circuit analysis, providing a strong foundation for further studies in electrical engineering.
What is mean by signal?
Signal is the electrical(discussion is confined to electrical domain only) quantity which varies between two levels and holds some useful information.
What did Stephen Gray invent?
Stephen Gray invented the concept of electrical conduction through different materials. He also discovered that some materials are conductors of electricity while others are insulators. His work laid the foundation for the development of electrical circuits and the understanding of electrical currents.
How many states do electrical circuits on an IC integrated circuit have?
Not possible to say without knowing much more. In analog circuits every signal has an infinite continuum of states. In digital circuits every signal usually has two states (some digital circuits have been built with three states), but there may be many many billions of these signals (e.g. 21,000,000,000 is an awful lot of states).
