Diod connected to circuit with A.C. allows current to pass in one direction only, where as capasitor smoothes changes in its magnitude. Diod bridge allows current directed in both directions to pass maintaining magnitude, but having one direction only. So, circuit with dioid bridge and capasitor makes AC as close to DC as possible while maintaining overall efficiency]]> 2018-12-07 05:15:08 UTC https://padlet.com/princess8/cvvpuf7wb2n1/wish/312117692 i(Olzhas) https://padlet.com/princess8/cvvpuf7wb2n1/wish/312117892 Alternating current is very effective and we can find lot of uses in our everyday life. Its truly impossible to vision world without alternating current, transformers, diodes etc.

2) Using solinoids with different number of terms, A.C. can effectivelly change its own voltage and current respectively.
3)Diod bridge convert a.c to d.c while adding capacitor can smooth a.c. values and get less energy losses ]]> 2018-12-07 05:17:51 UTC https://padlet.com/princess8/cvvpuf7wb2n1/wish/312117914 SHAH https://padlet.com/princess8/cvvpuf7wb2n1/wish/312118000 Alternating Current really effective in chanching voltage.

Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage.[1][2]The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, different waveforms are used, such as triangular or square waves. Audio and radio signals carried on electrical wires are also examples of alternating current. These types of alternating current carry information such as sound (audio) or images (video) sometimes carried by modulation of an AC carrier signal. These currents typically alternate at higher frequencies than those used in power transmission. https://padlet.com/princess8/cvvpuf7wb2n1/wish/312118254 2018-12-07 05:22:44 UTC https://padlet.com/princess8/cvvpuf7wb2n1/wish/312118254 https://padlet.com/princess8/cvvpuf7wb2n1/wish/312118267 2018-12-07 05:22:54 UTC https://padlet.com/princess8/cvvpuf7wb2n1/wish/312118267 My version: princess8 https://padlet.com/princess8/cvvpuf7wb2n1/wish/312139508 Transformers operate on the principle of electromagnetic induction. For real transformers, there are eddy currents, which are created by Faraday’s law due to the magnetic flux change that is naturally a part of AC circuits, which can be minimised by laminating the core. Though power transmission today is exclusively AC, most of the electronic devices we use today are of the DC variety. Thus, there must be a means to convert AC to DC within these devices. The conversion to AC to DC is made possible by a diode through the process called rectification. Further smoothing by the capacitor is required on the rectified DC so the voltage variation is not that huge.
