One. Measure the load resistance. Divide by five. Use that as the added series resistance. (For 1000 ohm load, add 200 ohms in series.)
Note that this answer may be wrong for situations where the load resistance changes or the current is high, as you must consider source to load rejection ratio and power consumed by the added resistor.
Another way is to to get a stabilised plug top power unit . Open it up and use the electronic regulator from it. Wire your 6 volts DC in place of the transformer secondary and use output as normal. The integrated three terminal regulator you are looking for is called a 7805 industry standard 1 amp regulator.
ANSWER: Must know the load current first then add a series resistor to drop 1 volts with the current flow.

If you have four batteries in series what is the output voltage?
depends on the voltage of the batteries.. four 12 volt car batteries would output 4x12 = 48 v
How do you link 12 volt batteries to get 48 volts?
You must hook them up in series. You will need four 12 volt batteries to do this.
Does Four 1000 Ohm resistors placed in parallel have a resistance of 250 Ohms?
Yes. The equivalent resistance of resistors in parallel is written as 1/Req=1/R1+1/R2+1/R3+... which, in this case, would be 1/Req=1/1000+1/1000+1/1000+1/1000=0.004. This means that Req=1/0.004=250Ohms.
How many mA in total when four AA batteries of 1.5 volt is combined?
depending on your load resistance what are you using . suppose you are using 100 ohm load resistance than current will flow 1.5*4=6/100=0.06Amp and if you are looking for battery current capacity than mind it you are using series connection the current will not change remain same as one battery but voltage will change as i mention above 6 volt.
Use the greatest common factor of 4 and 8 to reduce four eights?
The GCF is 4. The equivalent fraction is 1/2.
A student sets up a series circuit with four 1.5 volt batteries a 5-ohm resistor and two 1ohm resistors what is the total resistance in her circuit?
7 ohms (5+1+1)
What is the operation in using kelvin bridge?
A Kelvin bridge (as well called a Kelvin double bridge and in some countries a Thomson bridge) is a measuring instrument used to measure unknown electrical resistors below 1 ohm. It is specifically designed to measure resistors that are built as four terminal resistors.
If you have four batteries in series what is the output voltage?
depends on the voltage of the batteries.. four 12 volt car batteries would output 4x12 = 48 v
What are the ratings and certificates for Four Dead Batteries - 2004?
Four Dead Batteries - 2004 is rated/received certificates of: USA:R
How do you wire four 12 volt leisure batteries together to run 12 volt for my inverter?
To maintain the 12 volts using four batteries they have to be wired in parallel connections. This means that all of the positive posts are connected together and all of the negative posts are connected together. The total sum of all of the batteries will equal 12 volts.
What is the equivalent resistance of a series circuit that has four 5oo ohm resistors?
2000 ohms
How would reduce five to four without using any numbers?
By deleting the first and last letter of FIVE it becomes IV which is a Roman numeral for four.
What is the equivalent resistance of a pair of 8 ohm resistors in series circuit?
Two eight-ohm resistors in series would have a total resistance of 16 ohms. Two eight-ohm resistors in parallel would have a total resistance of four ohms.
How many amps in four C batteries in series?
C batteries use 1.5 volts. The number of amps depends on what device it is hooked up to. An average for four C batteries would be about 16 amps.
Is it normal to have pain and swelling in the face three to four days after a filling?
yes, it is normal. but you can reduce it by using ice packs
How does the effective resistance of four resistors in parallel compared to the individual resistance?
It depends on the values of the individual resistors. But if each resistor is identical, then the total resistance will be one-quarter that of an individual resistor.
Four resistors having a value of 100 ohms are connected in parallel what is the total resistance of the circuit?
What would the measured ohms be for two 100 ohm resistors wired in series? Two 100 ohm resistors wired in series measure 200 ohms.
