SUMMARY

The discussion centers on a relay circuit issue where the relay disengages approximately one minute after being activated. John reports that a 100 uF capacitor charges to 6 volts and discharges to 1.83 volts when the switch is pressed. The problem likely stems from insufficient voltage or current to maintain the relay's activation, suggesting a need for circuit adjustments or component replacements to ensure stable operation.

PREREQUISITES
  • Understanding of relay circuits and operation
  • Basic knowledge of capacitors and their discharge characteristics
  • Familiarity with voltage and current requirements for relay activation
  • Experience with circuit troubleshooting techniques
NEXT STEPS
  • Investigate relay specifications to determine minimum activation voltage
  • Learn about capacitor discharge curves and their impact on circuit performance
  • Research methods to stabilize relay activation, such as using a larger capacitor
  • Explore circuit design principles for maintaining relay engagement
USEFUL FOR

Electronics enthusiasts, hobbyists working with relay circuits, and engineers troubleshooting circuit activation issues.

Hey guys,

I am using the following circuit to switch on/off another circuit.

The problem is that for some reason the relay will disengage about a minute after it is switched on (although it seems to remain off indefinitely).

Does anyone have any ideas for what could be causing this?

Thanks,

John
