Scariest part of #UPSC prep is right here!. Worst? "I just need someone to hear me out". Too bad UPSC aspirants have no one to talk to about how they feel, always have good people around you. It is IMPORTANT for your mental health.

Some approx numbers of applicants in govt exams:. • RRB NTPC: 1.2 cr.• SSC CGL: 28 lac.• UPSC: 10 lac. <1% success rate, months of investment in prep and high rejections!. Do you not see a youth employment problem here?.

All of this 'complex' looking setup was changed in 1947 (yeah, tech came late to India tho! :P). How? SEMICONDUCTOR ELECTRONICS. • Phosphor replaced by Gallium-Arsenide-Phosphide (GaAsP) [light emitting material]. • Throws light as electron passes through. But future TV will.

Together, a CRT & MF solved for motion🫶. Okay CSEWhy but why MF & not Electric Field?. EF changes speed while MF?. It moves electrons faster in circular motion running in a uniform speed (just like a bullet)

It's like electrons flocking like a bird to a wall (screen). A bird signal manager direct birds towards different points on wall. This done regularly = MOVING PICTURE! 💡. Here, Cathode Ray Tube (CRT) solved for firing electrons. But how to DIRECT? MAGNETIC FIELD (MF)😮.

But here's a catch:. In Phosphor, entire screen will light up. How to have some parts light up while others stay dim?. CATHODE RAY TUBE. It reflects a picture but too fast that brain thinks it's a video! What's exactly happening?

You know CFL? The bulb? Same element was used in old TVs. It's called PHOSPHORS (diff from Phosphorus). When TV was 'started', P's fluorescent compounds excited to higher energy state. This emitted light (to start TV). When turned off,

TV changed fast, UPSC asked Qs faster!😉. How did 'screen' change over time?🤔. Electrons | Magnetic Fields | LEDs & more. India's fav dabba, goldmine for UPSC Q; . save to know entire story!🔖
