Consider the RC circuit shown in the figure below. If the resistance of the circuit is R=4kN and the capacitance of the initially uncharged capacitor is C=11µF. If emf of the battery the circuit is connected to is E=17V and the switch is closed at t=0, determine how long it would take for the capacitor to reach 86% of its maximum charge. Express your answer in units of ms (milliseconds) using one decimal place. + S

The duration of a photographic flash is related to an RC time constant, which is 0.12 us during the flash discharge for a certain camera. td = 0.12 us R = 0.048 ohm (a) If the resistance of the flash lamp is 0.048 ohm during discharge, what is the size of the capacitor supplying its energy in uF?
