If two impedances Z1 and Z2 are connected in parallel, then the total admittance and impedance are
1
\(\frac {Z_1Z_2} {Z_1 + Z_2}\) and \(\frac {Z_1+Z_2} {Z_1 Z_2}\) respectively
2
\(\frac {Z_1Z_2} {Z_1 - Z_2}\) and \(\frac {Z_1-Z_2} {Z_1 Z_2}\) respectively
3
\(\frac {Z_1-Z_2} {Z_1 Z_2}\) and \(\frac {Z_1Z_2} {Z_1 - Z_2}\) respectively
4
\(\frac {Z_1+Z_2} {Z_1 Z_2}\) and \(\frac {Z_1Z_2} {Z_1 + Z_2}\) respectively
