What this template does

This is a ready-to-run GetCalcMaster Notebook starter. Open it into Notebook, run once with defaults, then tweak inputs and keep your assumptions next to the math.

How to use it (recommended)

Open in Notebook.
Enter R and C (SI units).
Compute τ=R·C.
Evaluate V(t) at t=τ, 2τ, 5τ for intuition.
Graph V(t) in 2D Graph if desired.

Tip: When a result matters, verify it twice: a unit check + a second method (graph/estimate).

TEXT

# RC Time Constant (τ = R·C)

Charging step response (ideal):

**V(t) = Vin · (1 − exp(−t/τ))**

Rule of thumb: ~63.2% at t=τ, ~99% by ~5τ.
