Discussion Forum : Multivibrators and 555 Timer - General Questions (Q.No. 13)
13.
Determine tHI and tLO for the circuit given below.
tHI = 7.95 
s, tLO = 6.24 s
s, tLO = 6.24 stHI = 6.24 s, tLO = 7.95 s
s, tLO = 7.95 stHI = 3.97 s, tLO = 3.21 s
s, tLO = 3.21 stHI = 3.21 s, tLO = 3.97 s
s, tLO = 3.97 sDiscussion:

High time=ln(2)*C*(Ra+Rb)
Low time=ln(2)*C*(Rb)
All values given.. just subs
Low time=ln(2)*C*(Rb)
All values given.. just subs

High time = 0.693(Ra+Rb)*C.
Low time = 0.693*Rb*C.
Simply substitute with the given values.
Low time = 0.693*Rb*C.
Simply substitute with the given values.
