Question
I=Imax(1et/)
where , the inductive time constant of the circuit is equal to L/R.
Since the voltage across a resistor is given by VR=IR, the voltage across the resistor is also established exponentially:
VR=ImaxR(1et/)=V0(1et/)
Part A
What can we say about the term V0 in the equation for the voltage?
Pick the correct choices (there is more than one).
Part B
What is the voltage across the resistor when t=?
Enter the answer in terms of Vo. Enter any number that appears in your answer to 3 significant figures.
---
V_0 is the initial voltage across the resistor. V_0 is the voltage across the inductor. V_0 is the voltage provided by the power supply. V_0 is the voltage across the resistor when the current has reached its maximum value.Explanation / Answer
A)
V_0 is the voltage across the inductor.
B)
at t =
VR = V0(1e -/)
VR = 0.632 V0
