인덕터 vs 커패시터, inductor vs capacitor
| 축전기,capacitor | 유도기,inductor | |
| 전기용량,capacitance | 인덕턴스,inductance | |
| Differential $\displaystyle i-v$ | $\displaystyle i=C\frac{dv}{dt}$ | $\displaystyle v=L\frac{di}{dt}$ |
| Integral $\displaystyle i-v$ | $\displaystyle v_C(t)=\frac1C \int_{-\infty}^t i_C(\tau)d\tau$ | $\displaystyle i_C(t)=\frac1L \int_{-\infty}^{t} v_L(\tau)d\tau$ |
| DC equivalent | Open-circuit | Short-circuit |
| 둘 직렬연결 | $\displaystyle C_{\rm eq}=\frac{C_1C_2}{C_1+C_2}$ | $\displaystyle L_{\rm eq}=L_1+L_2$ |
| 둘 병렬연결 | $\displaystyle C_{\rm eq}=C_1+C_2$ | $\displaystyle L_{\rm eq}=\frac{L_1L_2}{L_1+L_2}$ |
| 저장된 에너지,energy | $\displaystyle W_C = \frac12 C v_C^2$ | $\displaystyle W_L = \frac12 L i_L^2$ |
