Homework Statement
An inductor of negligible resistance and an inductance of 0.2 H is connected in series with a 330 Ω resistor to a 12V d.c. supply. Determine:
- (b) the voltage drop across the inductor after two time constants
- (c) the voltage drop across the resistor after three time constants
Homework Equations
V=V*(1-e^(-tR/L))
The Attempt at a Solution
[/B]
I=V/R
I=12/330
I=0.036A
1. (b)
V=12*(1-e^(-2*330/0.2))
V=12V (obviously wrong)
Hi there, I think I might be a bit off with utilising this equation, I feel like I'm not plugging the values correctly/not using the correct values!
Any direction as to where I'm going wrong would be much appreciated!
Many thanks!
