At resonance, V_(L) and V_(C ) both very much greater than the applied potential, V itself. The quantity factor for an LCR circuit in resonance is given by Q = (X_(L))/(R ). In pratice, Q = 200 has been achieved. At resonance, the capacitor has been adjusted for (1). 200 xx 10^(-6) mu F (2) 0.00013 mu F (3). 0.0012 mu F (4). 0.0013 F At resonance, the potential difference across the inductance is (1) 1.3 V (2) 13 V (3). 0.3 V (d) none of these The potential across the capacitor at resosnance is (1) 1.3 V (2) 13 V (3) lt 13 V (4) none of these The Q factor is (1) (V_(L))/(V_(C )) (2) (V_(C ))/(V_(L)) (3) (V_(C ))/(V) (d) (V_(L))/(V) (e) choose the right statement. (1) V_(L)+V_(C) can be greater than V_("applied") (2) V_(L)+V_(C)=V_("applied") (3) V_(L)+V_(C) lt V_("applied") (4) none of these |
