    Off - On - Off timed circuit.

    Hi I was looking at your circuit and it looks like when the DPDT switch is in position 1 it activates the relay, and then when the capacitor is charged the relay is deactivated. When you switch to position 2, The first capacitor discharges to itself, and the second relay activates until the...

    Capacitor and LED question.

    Ok. I understand the first part, the red lines. And I understand the third part, the magenta lines. I also understand the need for resistors, next to the diagram the book says not to close both S1 and S2 for exactly the same reasons as you said. The green lines help to clarify some of my...

    Capacitor and LED question.

    I understand this part. This is when the capacitor is charging. The part I don't understand is when you close S2. This discharges the capacitor through LED2. Would the current not pass through LED1 after LED2 as it goes to ground?

    Capacitor and LED question.

    I tried adding resistors in various places and all that did was slow down the flashes. It still only flashed one LED or the other.

    Capacitor and LED question.

    When I think that the Capacitor is discharging, this is what I think its doing. S1 is open and S2 is closed obviously. Current is going from C1 through the switch, through LED2, through LED1, and then to ground. I have build the circuit, and this is obviously not happening. LED1 doesn't...

    Capacitor and LED question.

    Wait, I think I got it. Current flows from negative to positive, not positive to negative. So the current is going clockwise around the secondary circuit. Which would mean that the current wouldn't go through LED1. Right?

    Capacitor and LED question.

    Thanks for the reply. Let me see if I can clarify my confusion. I know that C1 discharges through LED2. My thinking is that as the capacitor discharges through LED2 that discharge would continue through LED1 as it goes to ground. Right?

    Capacitor and LED question.

    Hi, I am currently learning about capacitors. I came across a basic circuit that tries to explain the charge/discharge effect of a capacitor. Basically you push switch 1 and it charges the capacitor and makes LED1 flash. Then you push switch 2 and LED2 flashes as the capacitor charges. What is...
