a 100 mH inductor , a 20 uF capacitor and a 10 ohm resistor are connected in series to a 100 V , 50 Hz ac source . calculate (i) impedance of the circuit at resonance (ii) current at resonance (iii) resonant frequency


Dear Student,
                       (3)At resonance condition wL=1wCor w2=1LCw=1LC so resonance frequency=1.1×20×10-6=707Hz(1)and we total impendence=R2+wL-1wC2in cndition of resonance impedence=R (2) current =maximum voltage resistance=10010=10A
