Electric current flow heats up electronic devices. The generatedheatis dissipated and energy is lost. "For decades, people have been looking for ways to re-use this lost energy in electronics," explains Dr. Jamal Berakdar, a professor of physics at MLU. This is extremely challenging, he says...
As the electrons move from one point to another, they can do work. In an incandescent light bulb, for example, the energy of the electrons is used to create heat, and the heat in turn creates light. In an electric motor, the energy in the electrons creates a magnetic field, and this...
Geothermal energy is energy from within the earth. The earth from inside is too hot. This heat from within the earth can be used to turn turbines and produce electricity. This technology is still a subject matter of further research and engineering. Geothermal Energy How to Generate Electricity ...
Scientists agree that the human body, at rest, can produce around 100 watts of power on average. This is enough electricity to power up a light bulb. Some humans have the ability to output over 2,000 watts of power, for instance if sprinting. Which disease of the nervous system causes...
We can illustrate the concept of CD by considering the event when a shock in any variable of a country affects the same variable of the rest of the countries [67,68]. If CD remains untreated in the model, the results may produce spurious estimates [69]. Therefore, for producing reliable...

Electrical current passes through the heating unit, and electrical resistance causes the unit to get hot. It takes time for the heating unit to make the bit hot enough to use. It can also take a while for the bit to cool off again. This is partly because of the nature of heat itself...
To address this gap, we formulated the main research questions (RQs) of the current study as follows: RQ1: How can digitally enabled technologies be effectively used to obtain data and use data information in different lifecycle stages and promote product lifecycle management? RQ2: How can ...
In a small amplifier -- the amplifier in a speaker phone, for example -- the final stage might produce only half a watt of power. In a home stereo amplifier, the final stage might produce hundreds of watts. The amplifiers used in outdoor concerts can produce thousands of watts. The goal...
But the bigger the transformer, the bigger the current it carries and the more heat it produces. For a substation transformer like the one in our photo up above, which is about as wide as a small car, the waste heat can be really significant: it can damage the transformer's insulation,...
