special solenoid valve

In the diagram on the first link. The meter is shown across the capacitor. The voltage will ramp up just as described in the text and the graph. If the load were paralleled across the cap, and the load could be triggered with a 10K resistor in series with it, then yes it would act as a delay circuit. The coil of the relay would not energize until the voltage raised enough to energize the coil enough to pull the actuator. The 10K resistor is paralleled across the cap to discharge the cap between cycles. If you look at some of the delay relay circuits yo will notice that the resistor values are way lower than 10K.   The circuit as drawn MAY power an LED, but nothing more.

The first link does not say anything about Paralell circuits just series. Also AC acts different than DC. Now the second link does talk about Parallel RC Time Constants. Do your Math with that one.

In a nutshell what you are saying is that none of the12volt members know what they are talking about when they post these circuits that are varified by countless members all over the world. WE ARE NOT IDIOTS SIR. YOU ARE WRONG!!!!
