Problem 8.4-6 3 v 80k 2 uF + Harold E. Edgerton invented the electronic flash. An electronic flash on a camera uses the circuit shown above. Let's call the time at which the shutter switch is pressed t = 0. Before time t = 0, the capacitor charges to 3 volts. When the shutter switch is pressed the switch in this circuit moves to the right causing a current in the 80-822 resistor that represents the flash. The discharge of...
