Unformatted text preview: Conceptual Questions: 1) No the parameters that affect the inductance is the frequency reaches a certain value and the impedance will begin to increase. 2) ? Analysis: In activity 1 we measured the resistance of the coil using the mulimeter set at the most sensitive setting, which is ohm range. Resistance of the coil is the mulimeter reading minus the resistance of the wires which came out to be 5.3 (ohm). We then connected the RLC circuit board to the data interface on the computer. Attached a 10 (ohm) resistor and applied a constant 4.5 V to the circuit. When the applied voltage is zero, the current in the circuit decreased exponentially. This rate of decrease was our time constant which turned out to be 4.673 seconds. We were then able to find the inductance of the coil as well. We ran the test again but this time with a 33 (ohm) resistor and calculated a time constant of 2.14e-4 seconds. From the two tests we were able to calculate the inductance and found that the inductance from the two t rials should not be similar to each other because when...
