Electronics
In this section we'll discuss the three basic electronic components:
| Name | Unit | Symbol |
|---|---|---|
| Resistor (R) | Ohm (Ω) |  |
| Inductor (L) | Henry (H) |  |
| Capacitor (C) | Farad (F) |  |
Ohm's Law
RLC Impedance
| Impedance (Ω) | Low Frequency | Medium Frequency | High Frequency |
|---|---|---|---|
| Resistance, R | Doesn't depend on frequency | ||
| Inductive Reactance \$X_L = 2\pi f L\$ | Low | Medium | High |
| Capacitive Reactance \$X_C = \frac{1}{2\pi f C}\$ | High | Medium | Low |
RLC Addition
| Series | Parallel | |
|---|---|---|
Resistor, R [Ω] |  |  |
| \$R = R_1 + R_2\$ | \$\frac{1}{R} = \frac{1}{R_1} + \frac{1}{R_2}\$ | |
Inductor, L [H] |  |  |
| \$L = L_1 + L_2\$ | \$\frac{1}{L} = \frac{1}{L_1} + \frac{1}{L_2}\$ | |
Capacitor, C [F] |  |  |
| \$\frac{1}{C} =\frac{1}{C_1} + \frac{1}{C_2}\$ | \$C = C_1 + C_2\$ |
