Question

Three students x, y, and z performed an experiment for studying the variation of alternating currents with angular frequency in a series lcr circuit and obtained the graphs shown below. they all used

a.c. sources of the same r. m. s. value and inductances of the same value. what can we (qualitatively) conclude about the (i) capacitance value (ii) resistance values used by them

Answer 1

2.
$z = \sqrt{ {r}^{2} + ({xl - xc})^{2} }$
