🔍 Key Concepts

• Voltage division in series capacitors and how unequal capacitance or leakage can affect individual capacitor voltage • The role of a high-resistance shunt resistor connected across a capacitor in a DC power-supply filter • What happens to stored charge on capacitors in a high-voltage bank when power is removed

💭 Think About

• In a series string of capacitors on a high-voltage supply, what problem are designers trying to prevent by adding one resistor across each capacitor? • Think about the effect of a very large (high-value) resistor across a capacitor over both steady-state DC conditions and after power is turned off—what does it tend to do? • If one capacitor in the series has slightly different leakage than the others, how can a resistor across each unit help or not help with that issue?

✅ Before You Answer

• Consider whether the primary design purpose of these resistors is voltage balancing during operation, safe discharge after shutdown, or something else • Check if a high-resistance value would make the resistor good at quickly controlling voltage, quickly discharging, or just providing a small equalizing/leakage path over time • Ask yourself: does the presence of these resistors guarantee (or not guarantee) exactly equal voltage across each capacitor, or only tend to keep them reasonably balanced?
