Cathode Ray Oscilloscope | CRO

The Cathode Ray Oscilloscope is an instrument which we use in laboratory to display measure and analyze various waveforms of various electrical and electronic circuit.

 Working Principle:
CRO used Lissajous pattern to Display Traces on oscilloscope Screen.
Actually cathode ray oscilloscope is very fast X-Y plotters that can display an input signal versus time or other signal. Cathode ray oscilloscope uses luminous spot which is produced by striking the beam of electrons and this luminous spot moves in response variation in the input quantity. At this moment one question must be arise in our mind that why we are using only an electron beam? The reason behind this is low effects of beam of electrons that can be used for following the changes in the instantaneous values of rapidly changing input quantity. The general forms of cathode ray oscilloscope operate on voltages. So the input quantity that we have talked above is voltage. Nowadays, with the help of transducers. it is possible to convert various physical quantities like current, pressure, acceleration etc to voltage thus it enable us to have a visual representations of these various quantities on cathode ray oscilloscope. Now let us look at the constructional details of the cathode ray oscilloscope.

Construction of Cathode Ray Oscilloscope

The main part of cathode ray oscilloscope is cathode ray tube which is also known as the heart of cathode ray oscilloscope.
  1. Electron gun.
  2. Deflection plate system.
  3. Fluorescent screen.
  4. Glass envelope.
  5. Base.

Megger | Working Principle Types History Uses of Megger

History of Megger The device is being used since 1889, popularity raised during 1920s, since long back devise is same in its uses and purpose of testing, few real improvement appeared in recent years with its design and quality of tester. Now high quality option are available which are easy to use and quite safe. What is Megger? Insulation resistance quality of an electrical system degrades with time, environment condition i.e. temperature, humidity, moisture and dust particles. It also get impacted negatively due to the presence of electrical and mechanical stress, so it’s become very necessary to check the IR (Insulation resistance) of equipment at a constant regular interval to avoid any measure fatal or electrical shock. Uses of Megger The device enable us to measure electrical leakage in wire, results are very reliable as we shall be passing electric current through device while we are testing. The equipment basically use for verifying the electrical insulatio

history of Nehru–Indira Gandhi family

The  Nehru–Indira Gandhi family  is a prominent Indian political dynasty, which primarily consisted of Jawaharlal Nehru, Indira Gandhi and her descendants. Their political involvement has traditionally revolved around the Indian National Congress. Members of the family have traditionally led the Congress party and the Republic of India since independence. The Guardian  wrote in 2007 "The Nehru Gandhi brand has no peer in the world — a member of the family has been in charge of India for 40 of the 60 years since independence. The allure of India's first family blends the right to rule of British monarchy with the tragic glamour of America's Kennedy clan." The Gandhi surname came from Feroze Jehangir Ghandy, who was not related to Mahatma Gandhi. Indira Priyadarshini Nehru (the daughter of Jawaharlal Nehru) married Feroze Gandhi in 1942 and adopted his surname. Earliest record Raj Kaul (late 1600s to early 1700s) a Kashmiri Pandit, he is the earliest recorded
