why put a capacitor between signal and ground
1. the large capacitor is the normal ripple bypass capacitor which is intended for power line filtering
2. due to the high internal inductance of the large electrolytic capacitors it will has a bad high frequency filtering capabilites so we put a...
1. first for safety reason because the transformer introduce isolation from mains power supply.
2. the resistor or cap. in series does not introduce voltage regulation becauce the drop voltage will depends on current so if mobile works through charging voltage will be fluctuates
if one plate of capacitor is less in are than the other , which are takes the effect in capacitance value the large or small?
Added after 1 minutes:
i one plate of capacitor is less in area
question
if you need to built a cct in home, may be strip or vero board better for you
here is a good post for pcb :

the solid state relay is not an electromechanical device it is electronic relay may be of thyristor or triac or else. so there is no spark in the electronic relay during contact or release
challenge question ..
hi
i read your post and i say:
1. first one should know there are two types of energy kinetic and dynamic the first exist but you could not transform it to other type of energy like the dynamic one.
2. Secondly i say the the physics does not explain from where reasons...
