1. The duration of a photographic flash is related to an
RC time constant, which is 0.103 μs for a certain camera. If the
resistance of the flash lamp is 0.0364 Ω during discharge, what is
the size of the capacitor, in microfarads, supplying its
energy?
2.
Use the circuit above and Kirchhoff's Rules to determine
the current through the R3 resistor. Assume the following details:
E1 = 19.81 V, E2 = 44.64 V, r1 =
0.25, r2 = 0.4,...

8. Capacitance in circuits, RC circuits When a voltage source Vo is applied to a capacitor in a circuit which has a resistance R, a charge Q CV will build up across the capacitor. This does not happen instantaneously, but takes some time. The charge builds up exponentially with a characteristic time r = RC.
