Description: A multivibrator has identical components(capacitors, transistors and resistors) arranged on the left and right hand sides that can be used to implement a variety of simple two-state systems such as oscillators, timers and flip-flops. In a multivibrator circuit, increasing the value of the two electrolytic capacitors increases the time each LED remains on/off.
In the example given below, NPN transistors(BC547), capacitors and resistors have been used. This particular project can be used as LED blinker as well as astable timer for counter circuit.

Hello! Can the 47k resistors be replaced with something significantly smaller? Maybe 3k?
Yes. You can try that.
So it won’t explode or anything? And it’ll still work?
Comment: can u tell me the capacitor voltage value.
