Experiment 1

R = 300 + (1/300 + 1/300)-1 = 450 ohms
Our sine data was very close to a perfect sine wave. It met the expected amplitudes and resembled the sinusoidal function.
a.) V = IR; Voltage = Current x Resistance Yes, because based on the uncertainty it reflects that our measured value was relatively close to the actual values. Yes, ohm's law works on the with ac current and voltage based on the linear approximation of calculated slope in terms of R. The values (1025 and 939) are very close. Because they have a relatively same slope, it shows that ohms law is valid.

Experiment 3

The reason why putting brass in the coil did not induce a current is that brass is not magnetic. Therefore it does not create a magnetic field inside the coil and therfore no change in flux is generated. The iron produces a larger induced current and since iron is magnetic, it does generate a magnetic field inside the coil and therefore changes the magnetic flux inside the coil and the coil then generates a current to oppose that flux.

According to Faraday's law you need a change in the magnetic flux to induce a magnetic field. Because the wire is not moving, there is no induced magnetic field.

Initially the small coil inside the large coil genrates a change in magnetic flux through its inherent current. The large coil then generates a current to oppose that flux, which represents the initial spike in the graph. The decrease in voltage is due the large current opposing the flux and thereby reducing its voltage. Once the voltage reaches zero, there is no flux to oppose the change generated by the small coil, which is why the voltage spikes again, this time in the other direction due to the nature of the square wave voltage.

The electric field is reduced by a factor of cos theta after the light passes through the polarizer.
