Hi , thanx walid for your effort to reply Ok basically i am studying resonance. I am attempting to connect a non-polar 2.2 uf 250 V capacitor in parallel with a 4.6H coil. I want to connect it to a socket which supplies 240V 50Hz ac. My question to you is, will the circuit short circuit if i don't include a resistor? From what i was told that when it comes to using mains voltage there has to be some resistance or load otherwise there will be a short circuit,
