 The simulation results would show the output voltage across `R1` successfully "boosted" compared to the 5V input from `V1`. The specific output voltage depends on the duty cycle of the MOSFET driver `V2` and the component values.

+## Example: RC Charging Circuit
+
+Here's an example of an RC circuit that forms a voltage divider with a capacitor. This also functions as a low-pass filter. Since no `spiceEngine` is specified in `<analogsimulation />`, it uses the default `spicey` engine. Voltage probes are placed at the input and output to observe the charging behavior.
