Will this method theoretically reduce inrush current during relay turn on?

Here is a simulation for a relay closing at zero degrees, 125 amps peak: The peak current is limited because the input AC voltage starts at zero and charges the capacitor with a lower current over a ...

Will this method theoretically reduce inrush current during relay turn on?

A Zero Crossing Switch, ZCS circuit is a common solution to minimize the stress of step voltage in random phase for rectified voltage into large electrolytic capacitors. The surge current is limited ...

Does it make a difference if I use 8MHz or 16MHz crystal for PIC18F47J53

It depends on what limitations you have. For example higher freqency crystals can come in smaller packages than lower frequency crystals. And while it may not apply to the PIC MCUs specifically, but ...

Does it make a difference if I use 8MHz or 16MHz crystal for PIC18F47J53

I don't think there is a lot of difference, all other things being equal. Both are more-or-less in the optimal range for inexpensive and widely available crystals. Case size is probably a bigger ...

Does it make a difference if I use 8MHz or 16MHz crystal for PIC18F47J53

2 main differences, from the data sheet: 8 MHz clock will run at a slightly lower operating voltage than 16 MHz. 16MHz will run higher current. You have to extrapolate here, but more than double the ...
