A circuit is composed of a capacitor C= 3 micro F, two resistors both with resistance 69 Ohm, an inductor 6.00e2 H, a switch , and a battery 25 V. The internal resistance of the battery can be ignored . Reminder: The " L=x.xxenn H" notation means " L=x.xx X 10^nn H".
Initially, the switch S is open as in the figure above and there is no charge on the capacitor and no current C flowing through the inductor L . At t=0 we close the switch.
Define the current through the inductor to be positive if it flows through the inductor and then through the resistor and therefore down in the drawing. Similarly, define the current through the capacitor to be positive if it flows down in the drawing.
What is the current through the inductor (in Amps) at t= 0 (i.e. just after the switch is closed)?
