Effect of cable capacitance Q)What is Effect of Cable Capacitance on the Operation of AC operated Contactors When long length of cables is used the stored energy in the capacitance of the cable holds the contactor even after the closing command is removed . Typical value of capacitance for two core cable is 0.3 micro farad/km Fig:Stray capacitance Remedy: 1) Use of DC control supply voltage 2) Use of lower supply voltage 3) Short circuiting of contactor coil during off command by additional bridge contacts. 4) Use of large contactors .......

This is an audio effect circuit that give extra oscillation to your guitar, percussive, or semi percussive instruments, you can call it a funk box. This  guitar effect circuit is basically a damped oscillator that is set slightly below its critical oscillation point.   The oscillator part is constructed by feeding back the output signal through a bandpass circuit, with the center frequency is adjusted by potentiometer R7 to add an extra “twang” , adjustable from low to high pitched timbre. Potentiometer R4 is used to adjust the gain of the oscillator, should be set to damp the oscillation at the desired decay time.   To adjust it, turn the knob slowly until a steady oscillation occurs, and turn back slightly just before it happens (the oscillation should ceases slowly). Here is the schematic diagram of the circuit. Funk (Twang) Guitar Effect Box Circuit Diagram
