# Regarding reservoir capacitor in diode bridge [duplicate]

In my recent physics lab I constructed and examined the diode bridge (see https://en.wikipedia.org/wiki/Diode_bridge#Output_smoothing).

In particular I was interested in the smoothing properties of the capacitor. However when adding the capacitor ($300 \mu F$) and measuring the voltage (continously, using voltage probes over the resistor) I noticed that the resultant voltage curve was only smoothed by certain resistors.

This might be a basic question concerning the behaviour of current, but why will certain low-ohm resistors (I believe I used a 100 $\Omega$ resistor) result in a (unchanged) pulsating voltage while other high level resistor (for instance 10000 $\Omega$ resistor) creates the intended smoothing?
