Admittance Formula:
| From: | To: |
Admittance (Y) is a measure of how easily alternating current (AC) flows through a circuit. It is the reciprocal of impedance (Z) and is measured in siemens (S). Admittance represents the total ability of a circuit to conduct current, including both conductance and susceptance components.
The calculator uses the admittance formula:
Where:
Explanation: Admittance is simply the reciprocal of impedance, representing how easily current flows through a circuit compared to the opposition presented by impedance.
Details: Admittance calculation is crucial in AC circuit analysis, power systems engineering, and electronics design. It helps in analyzing parallel circuits, transmission lines, and understanding the overall behavior of complex electrical networks.
Tips: Enter impedance value in ohms (Ω). The value must be greater than zero. The calculator will compute the corresponding admittance in siemens (S).
Q1: What is the difference between admittance and impedance?
A: Impedance (Z) measures opposition to current flow, while admittance (Y) measures how easily current flows. They are reciprocals of each other: Y = 1/Z.
Q2: What are the units of admittance?
A: Admittance is measured in siemens (S), which is equivalent to mhos (℧).
Q3: When is admittance used instead of impedance?
A: Admittance is particularly useful when analyzing parallel AC circuits, as admittances in parallel add directly, making calculations simpler.
Q4: Can admittance be complex?
A: Yes, admittance can be complex, consisting of real part (conductance, G) and imaginary part (susceptance, B): Y = G + jB.
Q5: What is the relationship between admittance and conductance?
A: Conductance (G) is the real part of admittance and represents the ability to conduct real power, while susceptance (B) is the imaginary part representing reactive power flow.
