Capacitance and voltage relationship

Click For Summary
SUMMARY

An increase in capacitance does not inherently mean a decrease in voltage; rather, it depends on the circuit configuration and the charge on the capacitor. According to the formula V = Q/C, if the charge (Q) remains constant, an increase in capacitance (C) will result in a decrease in voltage (V). However, the specific context of the circuit, such as whether capacitors are arranged in series or parallel, significantly influences the voltage behavior. Additional factors like safe working voltage and voltage drop must also be considered for accurate analysis.

Does an increase in Capacitance mean a decrease in voltage?
Thanks!

If the charge on the capacitor doesn't change the voltage will decrease. (V = Q/C). If it does change it depends on the circuit and what you do to it.

Thanks!

Even adding that they are in series isn't enough information.

You could mean:

The safe working voltage
The voltage drop through them
The voltage between the ends and ground
or??
 
Thread 'Colors in a plasma globe'
I have a common plasma globe with blue streamers and orange pads at both ends. The orange light is emitted by neon and the blue light is presumably emitted by argon and xenon. Why are the streamers blue while the pads at both ends are orange? A plasma globe's electric field is strong near the central electrode, decreasing with distance, so I would not expect the orange color at both ends.
