उत्तर
| Feature | Inductive reactance (XL) | Capacitive reactance (XC) | Impedance (Z) |
| Definition | It is the opposition an inductor offers to the flow of AC. | It is the opposition a capacitor offers to the flow of AC. | It is the total effective opposition of the entire circuit (R, L and C). |
| Formula | XL = 2π f L | XC = `1/(2 pi f C)` | Z = `sqrt(R^2 + (X_L - X_C)^2)` |
| Frequency effect | It increases linearly with frequency (f). | It decreases as frequency (f) increases. | It depends on the combined effect of R, L, and C components. |
| Phase relationship | Voltage leads current by 90°. | Current leads voltage by 90°. | The phase angle ranges from 0° to 90° depending on the components. |
