1.7 Transients

Outcome 7 of 9 in domain 1 · Foundations, direct current

RC, RL, time constants.

My targets

I declare:

Calculate the time constant of an RC and an RL and say what it means (63 %, five time constants).
Plot a capacitor charging on the oscilloscope and recover RC.
Explain why a button bounces and how an RC filters it.
Size an RC for a given delay, build it and measure it.
Explain why a capacitor blocks DC and passes change, and use it to couple two stages.
Diagnosis: a circuit that starts "too fast" or "too late", find the time constant at fault.
