An RL circuit looks harmless.
A resistor, an inductor, a DC supply, and a switch.
But that simple circuit explains a lot of real engineering problems: relay pickup delay, solenoid response, brake coil release time, MOSFET failures, contact arcing, and inductive kickback.
The key number is the RL time constant:
τ = L / R
RC timing looks easy. Pick a resistor. Pick a capacitor. Multiply them. τ = R × C Enter...
If you work with radio, the chances are that before too long you’ll be winding an inductor. At radio frequencies these won’t be…

For a long time, I had a simple rule in my mind: high current means fault. If a transformer suddenly...
