How to use capacitors in a Solenoid circuit
In the time since this post, I attempted to use a relay module to control the circuit rather than any capacitors at all. However, I think I am realising that the relay module can''t actually stay on for 20ms, by design. It can only

View more6 FAQs about [Has the relay stone ever been used with a capacitor ]
Why does my relay have a capacitor across the coil?
A capacitor across the relay coil will draw a large current surge when the relay is being energised. This surge of current may damage the driving circuitry or cause a drop in the supply voltage which will upset the circuit in other ways. Yeah I thought it would be across the coil I just thought it best to double check.
Why do relay coils have resistors?
The presence of resistor reduces power-saving effect. To apply the rated voltage to the relay coil for 100 ms, a voltage higher than 100% of the coil’s rated voltage must be applied to the circuit. Increased capacitance of capacitor.
How to apply rated voltage to a relay coil for 100 ms?
To apply the rated voltage to the relay coil for 100 ms, a voltage higher than 100% of the coil’s rated voltage must be applied to the circuit. Increased capacitance of capacitor. The circuit voltage is divided according to the state of charge of the capacitor.
How do you connect a capacitor to a relay?
In both cases, you will connect the capacitor in parallel with the relay as when the power is switched off the relay will stay energized for a few seconds. The time it will remain energized depends on the capacitors value, the resistance of the relays coil and the pull-out voltage of the relay.
How long does a capacitor stay energized?
The time it will remain energized depends on the capacitors value, the resistance of the relays coil and the pull-out voltage of the relay. For "C=capacitance of capacitor " is the units μf (microfarads) of F farads ??
Would a relay need a resistor?
Would it need a resistor? If you are going to use a voltage higher than 12V to power the relay you will need a resistor in series with the relay coil to limit the current through it to a safe value and do not destroy the relay. If you will use a 12V supply connect the relay coil directly to it.
