The day began with an ActivPhysics activity 14.1 called The RL Circuit. It was a circuit with resistors and inductors. We began solving some problems until Mason told us to stop because he thought we had done it before (which I do not think so) and so we moved on to another RL circuit which dealt with a closed circuit involving resistors and inductors with a switch and a 45 V battery. We solved for the torque of the inductor, voltage and current at the different points of the resistors and inductors. We also talked about how long the inductors would take in order to charge fully and how long they would take to charge to a certain point.
Using a previous 110 turn inductor (for which we calculated the inductance of) we tried to see whether our measurements could result in almost the exact amount of turns which it did not as seen below because we assumed many of the variables (which we always do haha).
Below is a picture of the set up we had in order to measure the current output made by the function generator and the closed circuit shown in the next picture. The waves indicate that the current reaches a certain point and then it it looses charge and then it repeats but I do not believe we got the correct function.
Below is a picture of our set up and how we connected the whole thing in series except for the resistor because that was in parallel with the inductor.
After Mason helped us out, the function shown below is what the actual outcome should be showing that as current goes through the charge reaches a maximum point and then resets every time a current goes through.
Below is a picture of the new set up that actually worked for us.
Next we talked about inductance and solved some more problems regarding inductance involving finding certain variables like resistance, inductance and the period of it.
Overall, the main emphasis of the day was to sharpen our skills regarding inductance and also the time it took for an inductor to reach max capacity.
