H (Henries = V·s/A)
The property of an electrical conductor or coil whereby a change in current induces an opposing electromotive force in the conductor itself.
E = -L (dI/dt), L = N Φ_B / I
Semiconductor Diode
Electromagnetism & Electronics
A (Current), V (Voltage)
A two-terminal semiconductor device formed by a p-n junction that allows electric current to flow easily in one direction while blocking it in reverse.
I = I_s [exp(e V / (k_B T)) - 1]
Series Circuit
Electromagnetism & Electronics
Ω (Ohms)
An electrical circuit topology in which components are connected end-to-end sequentially along a single continuous current path.
R_total = R₁ + R₂ + R₃, I_total = I₁ = I₂ = I₃
Solenoid
Electromagnetism & Electronics
T (Tesla)
A long helical coil of insulated wire that produces a uniform interior magnetic field when an electric current flows through it.
B = μ₀ n I (where n = N / L)
