Hi,
Was hoping someone could help me.
I have the following RL circuit:
20V input
8.2kohm resistor and 50mH Inductor in series.
Determine time constant:
I answered with: T = L/R 50mH / 8.2kohm
= 6.09 uS
Is this correct?
The question I am stuck on is:
Determine the value of VL after 1.5 time constants?
I have the formula, VL = E ( e - t / T)
I can't work out what to put for the t? I tried putting in:
20 (e - 1.5 / (6.09uS) but can't be right?
If someone could help I would be much appreciated
Thanks!
