Question

what is the value of time period of a IC 555 multivibrator?

​

Answer 1

Answer:

Astable Multivibrator using 555 – Design Theory

The time during which the capacitor C charges from 1/3 VCC to 2/3 VCC is equal to the time the output is high and is given as tc or THIGH = 0.693 (RA + RB) C, which is proved below.
