चार महीने का बच्चा कैसे बना अरब़पति

चार महीने का बच्चा कैसे बना अरब़पति? जन्म के सिर्फ चार माह बाद यदि कोई बच्चा अरबपति बन जाए तो इसे उसकी किस्मत ही कहेंगे। भारत के एकाग्रह रोहन मूर्ति नाम के बच्चे की किस्मत कुछ इसी प्रकार चमकी है। देश की दूसरी सबसे बड़ी आइटी कम्पनी इंफोसिस के फाउंडर नारायण मूर्ति ने सोमवार अपने चार महीने के पोते एकाग्रह मूर्ति को 240 करोड़ रूपए के शेयरों की हिस्सेदारी का तोहफा देकर उसे शायद देश का सबसे कम उम्र का अरबपति बना दिया है। BSE की फाइलिंग के अनुसार इंफोसिस में अब एकाग्रह रोहन की 15 लाख शेयरों की हिस्सेदारी हो गई है। इसका मतलब अब एकाग्रह रोहन इंफोसिस का 0.04% का हिस्सेदार है। शेयरों के स्थानान्तरण के बाद नारायण मूर्ति के पास कम्पनी के कुल शेयरों का 0.36% हिस्सा बचा है। जिस समय नारायण मूर्ति द्वारा अपने पोते को शेयर देने की खबर बाई उस समय इंफोसिस के शेयरों में गिरावट देखने को मिल रही थी। एकाग्रह रोहन, नारायण मूर्ति तथा सुधा मूर्ति के बेट रोहन मूर्ति और उनकी पत्नि अर्पणा कृष्णन का बेटा है। आपको यह पता होगा कि नोरायण मूर्ति ने अपनी पत्नि सुधा मूर्ति से 10 हजार रूपए उधार लेकर 1981 में इंफोसिस क

X-ray spectra | Quantum mechanics | Atomic and Molecular Physics

X-ray spectra X-rays X-rays were discovered by a German physicist Wihelm Conrad Roentgen in 1895 during the study of the properties of cathode rays. These rays are actually electromagnetic rays of lower wavelengths having range from 10 Å to 0.5 Å. Higher wavelength side X-rays are soft X-ray and the lower wavelength side X-rays are hard X-ray. Properties of X-rays Since the X-rays do not deflect by electric and magnetic fields, hence they does not consist of charged particles. X-rays are electromagnetic radiation of very short wavelength. X-rays affect photographic plate like light, but their effect is much more intense than light. X-rays travel in straight lines with the velocity of light. They produce fluorescence in several materials. X-rays ionize the gas through which they pass. X-rays have high penetrating power and can pass through many solids. They produce photo electric effect also. X-rays also show in

Zener diode and voltage regulation

A device which is used to convert alternating current (or voltage) into direct current (or voltage) is known as rectifier, and the process of converting a.c. into d.c. is known as rectification. The voltage obtained from a rectifier depends on the input a.c. voltage. It means with the variation in the input a.c. voltage the output of a rectifier also varies, and it does not remain constant, hence we get an unregulated output. The method used to make the output d.c. voltage constant or stable is voltage stabilization or voltage regulation, and the device which is used to make the output d.c. voltage constant is voltage stabilizer or voltage regulator. The main application of zener diode is that it provide a constant d.c. output, so it is used in voltage regulator circuit. So in this session we have discussed about the zener diode and voltage regulation. This session is divided into two parts firstly we discuss about the voltage regulation, where we discuss about the line regulation,

Shunt capacitor filter

The output obtained from a rectifier is unidirectional, but it is not steady. The output of a rectifier is found to be in the form of pulse. It consists of a pure d.c. voltage with superimposed a.c. components, known as ripples. To remove the ripples or a.c. components available in the output obtained from the rectifier circuit, we introduce an electrical circuit between the rectifier and a load. This electrical circuit is known as filter. The filters minimize the ripples available in the output either by passing or blocking the a.c. components and provide an almost a constant output voltage. In this lecture we have discussed about the basic idea about filter, types of filters, and the complete description about the shunt capacitor filter. Since the lecture shunt capacitor filter is explained here in both Hindi and English language, so it is better to understand the student of Hindi and English mediums. This is bilingual lecture and is related to electronics.
