2) Construct the circuit shown using a 5V battery, resistor 100ohm,
Capacitor 10000uf, inductor and two switches (A & B)
3) For this Step we explore what happens when you open & close
Switch B (while Switch A stays open)
a) Make sure both switches are open and hit the Reset button.)
Add a scope for the capacitor.
b) Describe what happens when you close Switch B.
400Ω
c) What kind of circuit is it? (eg:RC/LC, charging/discharging)
d) What is the theoretical time constant for this circuit?
e) Use the mini graph from the scope to verify the time constant, similar to what you did for the RC Circuit (HINT: find time to get to 63% of max Voltage)
4) Now we charge up the capacitor and then discharge it into the inductor using the following:
Question 4 Setup:
i) first make sure to open both switches
ii) click Reset
iii) close Switch B until the capacitor is about 99% charged
iv) opening Switch B
You will use Question 4 Setup to reset the experiment for the rest of this question:
a) Add a second scope, this one on the inductor
b) Do Question 4 Setup then describe the behavior of the circuit. (use the scope) c) What kind of circuit is this?
d) Calculate the theoretical angular frequency (ω) of this circuit
e) Using the graph find the period of the circuit, and use it to find the angular frequency. f) Find the % difference between measured and theoretical angular frequencies
5) For this part we explore what happens when you add a resistor. a) Add a 50 ohm resistor in series with the inductor.
b) Do the Question 4 Setup & describe the behavior (use the scope) c) Make a plot of the maximum values (which is when the graph peaks above the x-axis) VS time using at least 5 maximum values
d) What does this graph show? In other words what is the meaning of this decaying maximum
