R-L

Refers to a circuit that contains both resistance (R) and inductance (L), affecting the phase and amplitude of the circuit's response to an AC input.

Exponential Curves

Graphs representing exponential functions, showing how values can grow rapidly due to constant proportionality rates.

Time Constants
