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
