Chapter 2.4: Admittance & Susceptance, Parallel AC Network

Admittance & Susceptance - How well an ac circuit allow current flow in the circuit. - The larger its value, the larger current flow. - Unit: Siemens (S)

Admittance & Susceptance (Cont…)

Admittance & Susceptance (Cont…) - For 2 impedance in parallel - For 3 parallel impedance

Admittance & Susceptance (Cont…) - Admittance for resistance

Admittance & Susceptance (Cont…) - Is a measure of how susceptible an element is to passage of current through it.

Admittance & Susceptance (Cont…) - Admittance for inductor

Admittance & Susceptance (Cont…) - Admittance for capacitor
