Introduction: This week’s lab introduces us on how to create a L/R circuit. The construction of the L/R circuit we will done with the Multisim . We will calculate the L/R time and use the transient to analysis the input and output of the RL voltage divider. Equipment/Components: Function generator 1 resistors: 1.5kΩ 1 inductor 10mH 1 capacitor 10pF Procedure: 1Part 1: Build the following circuit in Multisim. Use a square wave and 10 Vp in the function generator .

Calculate the L/R time constant (The ratio of inductance in henry with the resistance in ohms is the time constant in seconds). What is the time constant (L/R)? Use transient analysis to observe both the input and output of the RL voltage divider. Make a printout of the output. Initially the voltage across the inductor jumps to 20 V, there after the voltage decays exponentially to 0. Use the cursors to find the amount of time it takes to decay to 36.8% (1/e) of the original (20V) voltage. What is the measured time constant? Show simulation and

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
