Electrical – How is this circuit working? This is Flashing LED oscillator, I guess.


enter image description here

this is the video from where I got the idea to make it —
When one LED turns on, other turns off. Then the other one turns on. This proces is repeated. Now, I'm not sure how this oscillator circuit is even working. Please help me. I have to write its working in my practical copy. Help.

Astable Multivibrator

A multivibrator is an electronic circuit used to implement a variety of simple two-state devices such as relaxation oscillators, timers and flip-flops. It consists of two amplifying devices cross-coupled by resistors or capacitors. The first multivibrator circuit, the astable multivibrator oscillator, was invented by Henri Abraham and Eugene Bloch during World War I. They called their circuit a "multivibrator" because its output waveform was rich in harmonics.
