Need MATH help right away!

R is a constant for your lamp.

So you are correct, when put on 12v, the current will drop likewise 10 times. Power consumption goes down with the square of that. However, if you want the same amount of light produced by your lamp, you need to increase the current tenfold.

Series or parallel circuit and only the one +12 volt power supply ?

You say your lamp is a resistor and not a bulb so your voltage drop will remain constant but will only draw as much power or voltage drop as the amount of heat it can dissipate. An actual 12 volt bulb would use the current differently. If you have 2 power supply's you will have to remove one of them and do the math on the circuit for one then calculate the difference for the 2nd power supply.

In any even you have this circuit.

V ? = Ir * R or V = A * Ohms

The resistance can be found if the current and voltage are known. The current through a resistance is divided into the voltage across the resistance to find the value of the resistance. E/I/R E = I/R or R = E/I

Applied Source Voltage

I = E/R = E * (1/R) = E*G

Ohms = V over A.

So your circuit will be R= ER over 1R depending on your applied source.

Basic power formula is P = E2 over R and P = I2 * R

Or a proper hint would be an AC or DC power supply can deliver a maximum of 3A of current at 24 V so the maximum available power is 3A * 24V or 72 Watts of Power. Caution you could overheat this one unless you don't fuse it So much for your resistor.

In short dude available power is determined by using the PIE power formula. P = I * E

Keep your exponents simple and the circuit as series until you figure out the formulas or can remember them.

No I did not write that dhlucke I had you come over to my house and type it out for me.

You never learn do you. Besides any person I know accept for us are sane in the head and in bed.
So you do not in fact live anywhere near me. Besides your sig says you are an American boy. That doesent make you a bad person just handicapped.

However I can guess you are going to post that you are not retarded either. I just hope you can spell it again since you keep making that claim from time to time.

So are you saying that by being American I'm handicapped?

Question for you soddy WHEN THE [-peep-] DID GOD START LOVEING CANADA??? Cause I sure missed that ride.

Just a reminder Canada is a country going no where if god loved it I would be running it.

Listen son! You're stupid but think you know everything. You shouldn't have dropped out in the 8th grade. I know everything though.

I only know balls law

The angle of the dangle is directly proportional to the lust of the thrust, provided the urge remains constant.

Hehe, I actually figured out that P=V^2/R when I was using the other two equations. It's been a while since my physics classes!

But it's nice to speak with a fellow human!
