Do I need to install a reactance in front of the capacitor
Our products revolutionize energy storage solutions for base stations, ensuring unparalleled reliability and efficiency in network operations.
Unlike resistance, reactance does not dissipate heat when it opposes the current. It opposes the current in different way. A capacitor has both resistance and reactance, therefore requiring complex numbers to denote their values. Reactance in capacitor is created due to current leading the voltage by 90°.

Do I need to put a resistor in series with relay coil?
$begingroup$ Hi, Regarding: "If you are applying a voltage less than the relay''s rated coil voltage [...]the relay will also not switch [...]In that case, IMHO we can''t say that the relay "will not" switch for any lower voltage. As an extreme example, let''s say for a 12 V relay, then applying a voltage slightly less than that (e.g. 11.9 V) will still cause it to …

Fundamentally knowing when to use capacitors / inductors
If we need to stop the flow of current in a specific direction we know that we need to use a diode. If we need to block DC we use a capacitor. If we need to block very high frequency AC we use an inductor. If we need to design a filter we (can) use resistors, capacitors and inductors (and op-amps and transistors etc..)
