Capacitors



Those with electrical and CBL background help me out here. I had students
charge up a capacitor (10 microF) in series with about a 1 megOhm R with a
9V transistor battery. They measured the voltage on the cap with a CBL at
about 2 samples per sec and get a very nice 1-exp curve which levels off
nicely after a few seconds. But it levels of at a voltage much lower than
9V (around 5V)! Am I missing something? Shouldn't the final voltage be 9V?
Is there something about the CBL which would prohibit doing this? It seems
to be about the same for each setup.
