The reason is that, when voltage or potential difference is applied across an inductor, the electric current flowing through an inductor produces a magnetic field. This magnetic field again creates an induced electric current in the inductor but of opposite polarity, according’s to Lenz’s law....
A time-varying electric current produces electromagnetic waves, which are used in telecommunications to broadcast data. AC vs DC Current Based on the flow of charge, the electric current is classified into two types, i.e., alternating current (AC) and direct current (DC). AC Current The flow...
It's thought that such a powerful magnetic field might turn a photon into an axion, thus revealing the hypothetical particle to be real. Researchers are trying to tackle dark matter from all sides to uncover whatever information they can. But why is dark matter so important? If it's so ...
then you need to work through the layers of the crust till you get to the core. Every planet, including the gas giants, is believed to have a core. Earth has a molten iron core that generates heat and produces the protective magnetic fields that protect us from the Sun's harmful rays....
As people’S awareness of protecting and guarding the earth becomes stronger, an increasing number of people from different fields will join to live sustainably and eventually make the world a more worthy place to live. 第三套 作文题目: More and more people take the delight to helping the nee...
Loaded the question to trick the witness. Force To rape. Load To raise the power demand in (an electrical circuit), as by adding resistance. Force To induce change in (a complex system) by changing one of its parameters Greenhouse gases that force the earth's climate. Load To increase (...
Now, let the input voltage E, is applied across the brushes.Electric currentwhich flows through the rotor armature via brushes, in presence of themagnetic field, produces a torque Tg. Due to this torque Tgthe dc motor armature rotates. ...
