This circuit is used to measure the speed of a bullet with elements of the following values: Vo = 100 V, R= 25 N, C = 100 µF, d = 10 cm. R A B V. R C I d. Initially, the capacitor is charged, then the bullet cuts wire A disconnecting the battery, and later cuts wire B, leaving the capacitor isolated, whose potential difference, once both wires have been cut, is Vo / 4 a) Calculate the potential difference across the capacitor before the bullet cuts the wires, assuming the battery has been connected for a long time (show all steps). b) Determine the speed of the bullet (show all steps). c) Plot the current through the capacitor as a function of time (show all steps).

What is the effect of increasing voltage source frequency on the reactance of a capacitor? decreases the reactance O increases the reactance has no effect O destroys the capacitor

Regarding this circuit I was wondering what is the current / voltage relationship with the inductor and capacitor ?

You charge a capacitor and then discharges it through a resistor. You notice that, after four time constants, the voltage across the capacitor has decreased to _____ of its value just prior to the initiation of the discharge. Group of answer choices 0.135 0.368 0.00674 0.0183 0.0498
