Experimentally, the magnetic flux PB in a solenoid was 2- measured for various currents I. The data was recorded in the table and plotted in the graph. The best fit line through the data was also drawn. Current Magnetic flux (A) (Wb) 1.50 0.500 3.50 1.00 5.00 1.63 What is the inductance of the solenoid? Current (A) inductance: H Magnetic flux (Wb)

ew Policies how Attempt History Current Attempt in Progress Your answer is partially correct. A solenoid having an inductance of 6.05 µH is connected in series with a 1.17 k2 resistor. (a) If a 18.0 V battery is connected across the pair, how long will it take in seconds for the current through the resistor to reach 80.7% of its final value? (b) What is the current through the resistor at a time t = 1.00TL? (a) Number (b) Number 8.504 Hint 9.72E-3 eTextbook and Media Units times Units A Save for Later Last saved 1 hour ago.

Your RL circuit has a characteristic time constant of 21.5 ns, and a resistance of 5.40 MΩ. A. What is the inductance (in H) of the circuit? B. What resistance (in MΩ) should you use (instead of the 5.40 MΩ resistor) to obtain a 1.00 ns time constant, perhaps needed for quick response in an oscilloscope?
