You kept the switch in position 2 for a long time. Then you flipped the switch to position 1 and measured the voltage across the capacitor as a function of time (the magnitude of the voltage is recorded below, don't worry about the sign). The resistance R has been previously measured as 102 fi, and the battery used is 9V. Given the data below, what is the time constant of this exponential function (where the voltage across the capacitor is...

In the figure, the battery has an emf of 12.0 V, the inductance is 2.81mH and the capacitance is 9.00 pF. The switch has been set to position a for a long time so that the capacitor is charged. The switch is then thrown to position b, removing the battery from the circuit and connecting the capacitor directly across the inductor. a. Find the frequency of oscillation of the circuit. b. What are the maximum values of charge on the...
