Question

Use the following PhET simulation to complete the experiment. Include this document, figures, and typed summary (Part 4) in your submission. https://phet.colorado.edu/en/simulation/circuit-construction-kit-ac-virtual-lab Par-LC Circuit 1. Create a circuit with a battery and a capacitor inseries to charge the capacitor. Right click the capacitor, click Change Capacitance, and note down the capacitance. 2. Press pause at the bottom of the screen and disconnect the battery and remove it from the simulation 3. Connect an inductor in series with the capacitor. Right click the inductor, click Change Inductance, and write down the inductance. Press play arrow. Note any observations you see. I 4. Click Current Chart and place the detector on a wire in the circuit between the capacitor and inductor. Adjust the y-axis using the +/- arrows so that you can see the full sinusoidal curve and maximum current. Note the maximum/minimum current. To your best ability write down the period between maximum peaks. you can move the object around and see now the principal rays change. me on eac 10

Observations:

As soon as the capacitor is connected to inductor, a current starts flowing in the circuit, and the capacitor starts discharging. The capacitor takes some finite time to discharge completly, as soon as the discharge of the capacitor is complete, the capacitor starts charging again but with opposite polarity. On getting fully charge, the capacitor will again discharge sending current through the inductor in opposite direction(as plates have opposite polarities).

Time of first maximum peak T₁ = 178 s.

Time of second maximum peak T₂ = 192 s.

Hence,

Time period T = T₂ - T₁ = 192 - 178 = 14 s.
