When both switches are OFF, i.e. S=0 and R=0, the circuit latches the previous state of the outputs. For example, when SR=01, QQ' = 01 or when SR=10, QQ'=10 (refer to the characteristic table). Therefore when setting SR=00, the circuit output is either 01 or 10. As for where does the power comes fro...

RPM value never becomes stable and does not return to zero when rotor blades are removed. I made the circuit exa...
