1. for eg, capacitor is used for many purposes(it act as filter, oscillator, bypass capacitor, memory storage etc...) 2. Please tell me some example circuits for different uses of capacitor( whenever and whereever and however we used capacitor as a filter, oscillator tuning etc..) 3. similarly for inductor and resistors(it act as what?) and when and how we want to act as like that?, and how we can used these components depends upon our requirments with example circuits and explanation? design to act as these components depends

I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?

Is there a possibility to use such a treshold voltage for the NMOS part of a CMOS circuit that during the switching it will start conducting only after the PMOS part will be already closed, by this eliminating the leakedge current? Please note, I'm not asking about the well bias in standby mode, but about the "antileakedge" measures during normal operation.
