what is a rectifier

The A-C to be rectified is connected to the primary P 1 P 2 of a step down transformer. S 1 S 2 are the secondary coil of the transformer, which are connected to diode and load resistance R as sh..

The detector rectifies the input signal. So, either the top or the bottom half of the wave is removed. A suitable filter removes the radio frequency of the rectified wave. A signal is produced which follows the envelope of one-half of the wav..

Some Important Forms of Alcohol - Absolute alcohol or anhydrous alcohol (100% alcohol) is prepared by adding a little benzene to the rectified spirit followed by distillation. Ordinary rectified spirit is called industrial alcohol. To ensure that industrial alcohol is not used f..

Shortening of the eyeball, that is, the eyeball becomes smaller Increase in focal length of the eye lens Let us now see how this defect is rectified. A long sighted eye forms image of a nearby object behind the retina. Thus, long sightedness is due to the decreased converging power..

Later, Henry Gywn-Jeffreys Moseley showed that the atomic number of an element is numerically equal to the number of electrons round the nucleus. The number of electrons in turn is equal to the number of protons in the nucleus. He suggested that atomic number is a more fundamental property of..

At times the eye is not able to focus the light coming from the horizontal and vertical planes. As a result, the horizontal and vertical views of an object will not be the same. Such a defect of the eye is called astigmatism. Astigmatism occurs when the eye-lens or the cornea or both are not perfec..

The fermented liquor contains 9-10% of ethanol and is called wash or wort. It is distilled in a Coffey still (Distillation of wash in a Coffey still) to remove water and other impurities present in wash . The Coffey still consists of two tall fractionating columns with perforated plates. Thes..
