“admittance(symbol: Y; unit: siemens)”的概念、定义、翻译、参考文献-科学参考

单词	admittance(symbol: Y; unit: siemens)
释义	admittance(symbol: Y; unit: siemens) Electronics and Electrical Engineering The reciprocal of impedance. It is a complex quantity given by $Y = G + j B$ where G is the conductance, B the susceptance, and $j = \sqrt - 1$ . Since impedance, Z, is given by $Z = R + j X$ where R and X are the resistance and reactance, respectively, then $Y = \frac{1}{Z} = \frac{1}{(R + j X)} = \frac{(R - j X)}{(R^{2} + X^{2})}$
