How fast does current build?

An ideal 0.50 H inductor is connected in series with a total resistance of 10 Ω and a DC source.

Find the circuit time constant.

Organize the givens & assumptions
  • L = 0.50 H
  • Rtotal = 10 Ω

Ideal constant inductor in a linear series RL circuit; stated resistance includes all series resistance.
