87 The circuit of Fig. 27-75 shows a
capacitor, two ideal batteries, two
resistors, and a switch S. Initially S has
been open for a long time. If it is then
closed for a long time, what is the
change in the charge on the capacitor?
Assume C = 10 µF, E, = 1.0 V, 82 = 3.0 Figure 27-75 Problem 87.

a flashing lamp, like those attached to
barrels at highway construction sites.
The fluorescent lamp L (of negligible
capacitance) is connected in parallel
across the capacitor C of an RC circuit.
There is a current through the lamp
only when the potential difference
across it reaches the breakdown volt-
