Some Cases of Parallel Connected Elements We have seen that the equivalent admittance of a number of parallel admittances is the sum of their admittances. (1) R and C in parallel. When resistance (R) and capacitance (C) are in parallel, the total admittance Y is the sum of admittances of the two components. Since the admittance for resistance is 1/R and that for the capacitor jωC,
(2) R and L in parallel. When resistance (R) and inductance (L) are in parallel, the total admittance Y is the sum of admittances of the two components. Since admittance for the resistance is 1/R and that for the inductor is  j/ωL, (3) R, L and C in parallel. For resistance (R), inductance (L) and capacitance (C) all in parallel,the total admittance Y is
