What is the purpose of connecting equal-value resistors across power supply filter capacitors connected in series?
The correct answer is D: All these choices are correct. What is the purpose of connecting equal-value resistors across power supply filter capacitors connected in series includes: equalize the voltage across each capacitor, discharge the capacitors when voltage is removed, and provide a minimum load on the supply. All three are purposes. For amateur radio operators, this is important for power supply design. Understanding this helps when using series capacitors.
Exam Tip
All three are purposes of equal-value resistors across series capacitors: equalize voltage, discharge capacitors, provide minimum load. When all listed purposes are valid, 'all of the above' is usually the answer. All are valid purposes.
Memory Aid
"All three are purposes of equal-value resistors across series capacitors: Equalize voltage, Discharge capacitors, Provide minimum load. Think 'A'll 'R'esistor purposes. All three are valid purposes. Important for power supply design."
Real-World Application
Equal-value resistors across power supply filter capacitors connected in series: They serve to equalize the voltage across each capacitor, discharge the capacitors when voltage is removed, and provide a minimum load on the supply. All three are purposes. This is the purpose - all of these functions.
