Transient Analysis of a Resistor- Inductor (RL) Circuit
1. INTRODUCTION
Electrical circuit analysis is done in order to allow the designer to verify his design and to predict the response of the system under varying conditions of load and excitation.

Its formula looks like this: T= L/R. Tau or lowercase t. Five time constants are required for current to reach 100% of its value. The time constant of t for the circuit in Figure 7.1 is 470 micro seconds.
The Current value of IL, through the inductor at the beginning of the charge cycle is 0 Amps, while, the end of the charging cycle was 10 mA. The voltage at V1 across the inductor and resistor in the beginning stages is 10 V and end with 0V. The inductor acts like an open circuit at the beginning of the charging cycle, ending appearing like a short circuit.

3. Questions related to Constructed Circuit.
a. How does self-resistance of the inductor affect the results?
The magnetic field created by a charging current in the circuit induces a
The objective of this lab was to observe the behavior of a capacitor while charging through a resistor. Overall, the objective of the lab was achieved since an exponential curve was obtained from a charging capacitor.
(b) Due to the fact that R1 and R2 are identical, what would you guess is the voltage across each resistor is individually? Why?
a. What is the CD’s value at maturity (future value) if it pays 10 percent annual interest?
a. Credit will only be given if you clearly show your work, and clearly indicate the final answer.
The parcel starts descending at 6000’ feet, the temperature at this height is 50.1 F, and is above the original LCL. The new LCL is at 6000’ feet as the parcel is starting its descent down the lee side of the mountain. The mixing ration to start to movement up the mountain was approx 18.9 g/kg and the descent capacity is approx 7.6 g/kg.
7. In a procedure developed to determine the percent zinc in post 1982 pennies, 50 ml of an HCl solution was used to react (dissolve) all of the zinc in the penny. To ensure complete reaction, the solution contains twice as many moles of HCl that is actually needed. What concentration of HCl should be used?
Provide detailed descriptions and show all calculations used to arrive at solutions for the following questions:
3) In the lower left of the screen is a meter for indicating electric potential, in volts, created by the charge that you introduced. Record the voltage and turn on “Plot”.
The variables been shown in the simulater are the voltage, current, and ressistance. V(volts) = I(Ampers)* R(Ohms).
b. How would you estimate the appropriate discount rate to be used in valuing the cash flows?
The two types of electrical circuits are series and parallel. Series circuits provide only one pathway of current flow, while parallel circuits provide multiple pathways of current flow. Unfortunately,
8. What is the difference between the effective refractory period and the relative refractory period?
In the book, “The Circuit” by Francisco Jimenez, some examples are given on how family and culture can influence one’s life. Family and culture can negatively affect a person’s life because in the narrator’s case, it can cause them to move away from their friends or work hard to support their family. For example, “As the last days of August disappeared, so did the number of braceros. Sunday, only one—the best picker—came to work. I liked him. [...] That Sunday was the last time I saw him. [...] The thought of having to move to Fresno and knowing what was in store for me there brought tears to my eyes” (Jimenez 2 and 5). In other words, the narrator had to leave because the harvesting season was over and they had to find another place to work.
d. How many creditors have made inquiries about Jessie Robinson 's credit? (0.5 points) N/A
c) What is the implied DSO at the end of March? At the end of June? What is the relationship between the DSO and the average collection period?
