Electrical power, Yes the stuff which shocks you

[Lost His Marbles Name]

Just wanted to throw some first day or 101 ohm's law's at you people.

wattage devided by voltage= ampere's
voltage times ampere's=wattage
Wattage devided by amperes=voltage
voltage devided by ampers=resistance
voltage devided by ristance=amperage
current times resistance=voltage
and many more
10,000,000,000,000,000,000 atoms running across a conductor equals one ampere.
If you have anymore questions feel free to ask.
There's alot to electric but I don't want to get over peoples heads as I always do.

Hey not to be a wiseass but this doesn't make sense. How can wattage devided by voltage equal two different things?

"wattage devided by voltage= ampere's
voltage times ampere's=wattage
Wattage devided by voltage=voltage"

 

[DrBDC]

Line 3 mistype he meant wattage divided by amperage=voltage

sorry I'm at work and didn't proff read it.

Dave, your mailbox is full, so here are the specs

Here are the specs on the white ones: http://ledshoppe.com/Product/led/LE1002.htm

Here are the specs for the blue:

Specifications
Size (mm) : 5mm
Emission color : Blue
Forward Voltage (V) : 3.2 ~ 3.6
Reverse Current (uA) : <= 30
Luminous Intensity Type Iv (mcd) : 6000
Life Rating : 100,000 Hours
View Angle : -10 Degree ~ +10 Degree
Viewing Angle : 20 Degree
Absolute Maximum Ratings ( Ta = 25 Degree )
Max Power Dissipation : 80mw
Max Continuous Forward Current : 30mA
Max Peak Forward Current : 75mA
Reverse Voltage : 5 ~ 6V
Lead Soldering Temperature : 240 Degree ( < 5Sec )
Operating Temperature Range : -25 Degree ~ +85 Degree
Preservative Temperature Range : -30 Degree ~ +100 Degree

I tried to get the voltages as close as possible to avoid power problems. I hope this is what you are looking for

That what I was looking for but your power sluppy is only for 200 watts and this adds up to 400 watts and then your putting this on a 2.5 gallon tank. Your crazy, know wonder Steve likes you.

 

[Chelsey]

I can get a different power supply, that's no problem. Ideally what I'd like to do is have an adapter like a phone charger connected directly to the LEDs so that I don't have that big box just sitting around. Since my Nano cube cracked and had to be replaced I have the ballast for the lights available too...would that work?

I am not good with electrical stuff AT ALL...I was going to have another person do the wiring for me all along because with my luck I'd fry ~500 LEDs or electrocute myself, neither of which would be very good :lol:

 

[Lost His Marbles Name]

They don't have much resistance so you have to alter the current with a resistor or 500.

Are we going to go over Kirchoff's Law next? This could be fun!

 

[Lost His Marbles Name]

Kirchoffs law sucks but it's the law.

 

[Lost His Marbles Name]

Now that I had time to think about it the Led system will have 40 watts of power cunsumption less the resistors if needed.

 

[Chelsey]

What? The LED system will have 40 watts instead of 400 watts? I'm so confused! :lol:

 

[Lost His Marbles Name]

80milliwatt is .080 of a watt, so .080x500 leds=40 watts Sorry I haven't had a good night sleep in a month and the Chicago trip mad thing worse, up partying and long drives.

 

[Chelsey]

No problem, Dave I wouldn't have the slightest idea what I'm doing :lol: So would I be better off using the ballast from my 24 gallon NC or the power supply?
