Admittance Formula:
| From: | To: |
Electrical admittance (Y) is the measure of how easily an electrical circuit allows current to flow. It is the reciprocal of impedance (Z) and is expressed in siemens (S). Admittance consists of two components: conductance (G) and susceptance (B).
The calculator uses the admittance formula:
Where:
Explanation: Admittance represents the ease with which alternating current flows through a circuit, combining both the conductive and reactive components.
Details: Admittance calculations are essential in AC circuit analysis, power systems engineering, and electronic filter design. They help in understanding how circuits respond to different frequencies and in optimizing power transfer.
Tips: Enter impedance value in ohms. The value must be greater than zero. The calculator will compute the corresponding admittance in siemens.
Q1: What is the difference between admittance and impedance?
A: Impedance is the opposition to current flow in AC circuits, while admittance is the ease of current flow. They are reciprocals of each other.
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 in parallel circuit analysis, where admittances add directly, making calculations simpler than with impedances.
Q4: What do conductance and susceptance represent?
A: Conductance (G) represents the real part of admittance (resistive component), while susceptance (B) represents the imaginary part (reactive component).
Q5: Can admittance be negative?
A: While the magnitude of admittance is always positive, susceptance can be negative for capacitive circuits and positive for inductive circuits.
