Question

Part A You are analyzing an ac circuit that contains a solenoid and a capacitor in series with an ac source that has voltage amplitude 80.0 V and angular frequency w. For different capacitors in the circuit, each with known capacitance, you measure the value of the frequency wres for which the current in the circuit is a maximum. You plot your measured values on a graph of versus 1/C (Figure 1). The maximum current for each value of C is the same, you note, and equal to 4.50 A Calculate the inductance of the solenoid Express your answer using two significant figures IH Submit equest Answer Part B Calculate the resistance of the solenoid Express your answer with the appropriate units Figure 1of1 R= Value Units 3.00 2.50 2.00 1.50 1.00 0.50 Submit equest Answer Provide Feedback 1.00 2.00 3.00 4.00 5.00

Explanation / Answer

we know that

w2res = 1/(LC)

The slope of w2res vs 1/C   gives the value of "1/L"

hence

Slope = 1/L

AB/BC = 1/L

(3 - 2.25) (104)/((5 - 4) (103)) = 1/L

L = 0.133
