Capacitance

$$C = \frac{\epsilon A}{d}$$

Capacitor Charge

$$V = \frac{Q}{C}$$

Capacitor Current

$$I = C \frac{dV}{dt}$$

Capacitor Energy

$$E = \frac{1}{2} C V^2$$

Inductor Energy

$$E = \frac{1}{2} L I^2$$

Inductor Voltage

$$V = L \frac{dI}{dt}$$

Resistance in a straight conductor

$$R = \frac{\rho l}{A}$$

Shockley Diode Model

$$I = I_S \cdot (e^{\frac{V_D}{nV_T}} - 1)$$

Ohm's Law

$$V = IR$$
