Question About Audio Capacitor and (led) Lights on Them?

That's weird... I have some no name capacitor and the LED does stay on for a little while after I turn the car on, but then shuts off, until I turn the car back on. Not sure why yours continues to read the voltage... Do you have the cap going straight to the battery and grounded straight to the car? But as to your direct question, I do not believe it will kill your battery, I am sure it will drain it somewhat though. Many cars have flashing LEDs for there alarms and what not, and the batteries do not die

1. How to connect led lights together [picture diagram inside]?

Well, you will not have much of a light (for long) if you hook a 9 volt battery up to your present circuit. You have two basic options for hooking the LEDs up. Hook them up in parallel (not recommended) Hook them up in series. You pretty much lucked out doing this the first time. The 2 AA batteries with their internal resistances have limited the current such that you did not burn out your LED. The 9 volt battery however, will not have this limitation. Most LEDs need a forward voltage in the area of 1.2 to 1.5 volts to function. At the same time, they all have maximum currents and if you try to operate them with more current, they will burn out. Typically a current of around 20 milliamps is fine. It is possible that if you hooked about 6 of these same LEDs in series and then connected them straigth to the 9 volt battery, they may work and not burn out. However, normally one would look at the voltage drop of each diode and the required current and calculate the size of a current limiting resistor In your situation, start with 9 volts and then subtract the forward voltage needed to drive how ever many LEDs you use. Then divide that by the current and you have your resistor size.

2. Does LED lights have any effect on fish tank plants?

You do not have enough lights for your plants so do not buy anymore plants. Wait and see how the plants doing first before buying any more

3. TEST YOUR CHEMISTRY KNOWLEDGE! What is...?

Ha Ha. "Lighten up". I get it. AlGaAs is used in LED lights, which are far more efficient and consume less energy than standard incandescent light bulbs.

4. LED lights use less energy and last longer than incandescent but Trump says "No"?

Gas the Jew Trump. Trump screaming "AHHHH"

5. Is it wise to run 4 led lights at 20mA each to a 9 volt battery without a resistor.I know you can but should u?

no, not a good idea. Vf versus If is a curve with a very steep slope, that is, small changes in V produce large changes in I. You have no way of setting the current, it may be low, ie, dim light, or very bright, leading to destruction. In addition, Vf is very temperature dependent, and goes down with temperature dependent. So as the bulb warms up, Vf goes down, If goes up (a lot) which produces more heat, lower voltage, more current, a cycle that can continue until something burns out. .

6. My Frigidaire GLTF2940FS1 is plugged in but will not start nor will the LED lights come on?

Are you Positive the other outlet is Good? You may have tripped a breaker. Go and see. Also, a front loading washer, like yours and my Kenmore, wo not often do a thing unless front door fully closed and locked. My switch got broken once, I had to brace the door shut to make it work until I could get a new one. It could also be a GFI has tripped on the same line. Get a known working lamp or radio and try the outlets. Otherwise, let your Frigidaire cool off a while. It may have a thermal breaker inside. If it does not work after a few minutes rest on a good outlet, it may be toast. Especially if it tips a breaker .

7. questions about led lights hooked up to the amp?

you will desire to start via no longer being a cock and than rewiring is an insufferable torture reserved for under the worst of the international, and would in all hazard in simple terms be left to a individual who's paid to do it
