Will this electronic circuit work? (back-to-back polar capacitors)

Click For Summary
SUMMARY

The discussion centers on the viability of using back-to-back polar capacitors in AC circuits. It is established that while this configuration can work, the overall capacitance is halved compared to the individual capacitors. Additionally, safety considerations are paramount due to the potential hazards associated with the circuit. The thread was temporarily closed for moderation due to the dangerous nature of the topic.

PREREQUISITES
  • Understanding of AC circuits and their components
  • Knowledge of capacitor ratings, including voltage and current
  • Familiarity with back-to-back capacitor configurations
  • Awareness of electrical safety protocols
NEXT STEPS
  • Research the safety measures for working with high-voltage AC circuits
  • Learn about the implications of using back-to-back polar capacitors in AC applications
  • Study the effects of capacitance reduction in parallel capacitor configurations
  • Explore practical applications and limitations of polar capacitors in electronic circuits
USEFUL FOR

Electrical engineers, hobbyists working with AC circuits, and anyone interested in capacitor applications and safety in electronic design.

Get an AC rated capacitor with appropriate voltage and current ratings.
 
No, it will not work because there is no load.
If all you want to do is cook the capacitors you may be lucky.

Might work great as a one-time small explosive device.

@John1397 -- Please don't try to re-start your locked thread: https://www.physicsforums.com/threads/tv-capacitor-instead-of-motor-capacitor.1004111/
(that is against the PF Rules).

On the basic question of whether back-to-back polar caps can be used in AC situations, the simple answer is yes as long as you realize that the overall capacitance is half of the capacitance of each capacitor. There are more considerations, and since you are dealing with a dangerous circuit there are also safety considerations. This thread will remail closed on that basis.
