Question

what effect does the value R in the circuit have on the resonant curve

Current So Frequency FIGURE 47.6. Resonant frequency fo of an RLC series circuit. up for Resonance in an RLC Series Circuit etup for determining the frequency of resonance is basically the same R resonance, the current in the circuit reaches its maximum value. If a vill measure the voltage Vo Recall that the

Answer 1

Simply saying , as the R value decreases the current amplitude increaces with frequency.In frequency resonance cure decreaced R values makes the curve pointer upwards .Which results in sharper increace in current amplitude with frequency in X(c) >X(l) and Sharp decreace in amplitude with frequency at X(l )> X(c).
