Jia Zheng 111381607 Lab 7: Inductors Introduction: In this lab, we will be observe and measure the inductance of an inductor by three different ways, first, from first principles, using the geometry of the inductor; second, using an LR circuit; third, using an LC circuit. An inductor is a circuit component which resists a change in current. As the formula can be express by V L= -LI’(t). L= μ N 2 A l . For LR Circuits, LI’(t)=RI(t) =V0. I(t) =(I(0)−V 0/ R)^e −t/τ + V 0/ R . For LC circuits, LQ’’(t) + ( 1/C)Q(t)=V 0, Q(t)=CV 0 +(Q(0)−CV 0 )cos(ω 0 t)+ (I(0)/ω 0) sin(ω 0 t). As using the Kirchhoff’s Law to derive relationships between voltage, current, and resistance in each circuit element. An LRC circuit is an electric circuit that consists of a resistor, an inductor, and a capacitor, as it connected to either series or parallel. This is example of a resonant circuit. In a circuit, without the inductor, the voltage would be conserved, although my hypothesis is that there will be a logarithmic relationship between voltage and time. Producer: 1. The experiment materials include 1 Oscilloscope, 1 Function Generator ,1 Solenoid Coil, 1 Decade Resistor , 1 Decade Capacitor, and Banana cables (8) and alligator clips (8) 2. We Measure the length and diameter of your solenoid. 3. As we connect the circuit in an LR circuit, the wiring a red wire from the red terminal on the function generator to the red terminal of the decade resistor. We link the wire from the black terminal of the resistor to the left-hand side of the inductor. A black wire from the

    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.
