What would replace a Sony Cr 2032 battery?
another CR2032 battery (from a different brand) would work flawlessly. if you are asking about substitutes, than any 3v or pair of 1.5v batteries would work, as long as you could fit them inside the device. Some brands called the same batteries as 2032. You can check out the <a href="http://www.24hrbatteries.com/shop/pcs-lithium-2032-battery-free-shipping-p-92.html">2032 Lithium Battery</a> here.
What resistors are required to convert 12volts Dc to 3 volts dc?
In general terms, the voltage across a resistor can be calculated by ohms law: V = I . R voltage across the resistor = current through the resistor multiplied by the value of the resistor. So, if the resistor has a value of 100 ohms and the current flowing through the resistor is 10mA then the voltage across the resistor will be 100 x 0.01 = 1 volt. If the current flows through two resistors connected in series, the voltage will be split over the two resistors according to their resistance. V = V1+V2 = I . R1 + I . R2 You want V2/(V1+V2)=3V/12V Using Ohm's law for each voltage: V2/(V1+V2) = I . R2 / (I . R1 + I . R2) = R2 / (R1+R2) You see that the answer to your question is: Any combination of resistors will do the job, provided that R2/(R1+R2) = 3V/12V e.g. R2=3Ohm and R1=8Ohm or R2=3000Ohm and R1=8000Ohm Depending on your choice, you will get a different current flowing. In the real world you might need to control the current flowing into your circuit. For example if the device to be powered is a 3V LED and the required current is 15mA then we can calculate as follows: 12V - 3V = 9V. 9V = 0.015A x R Therefore R = 9V / 0.015A Therefore R = 600 ohms. However, in real life this is usually a terrible way to control voltage for several reasons. First, because the current in the most circuits is not constant (it would be constant for an LED but not for most gadgets). Second, this method wastes energy heating the resistor. Third, it is often not possible to find a resistor of exactly the right value. So, in real life this problem is usually solved by using a "voltage regulator" which is a simple integrated circuit (often with just three legs).
List four symptoms that indicate a faulty power supply?
1) The power reading (battery moitor) changes frequently, up and down, or is always unsure 2) The computer shuts down through loss of power when it seems to be on full power 3) the power cable is damages, very old or has been faulty in the past It takes some experience to know when this type of failure is power related and not caused by the memory. One clue is the repeatability of the problem. If the parity check message (or other problem) appears frequently and identifies the same memory location each time, I would suspect that defective memory is the problem. However, if the problem seems random, or if the memory location the error message cites as having failed seems random, I would suspect improper power as the culprit. The following is a list of PC problems that often are related to the power supply: * Any power-on or system startup failures or lockups. * Spontaneous rebooting or intermittent lockups during normal operation. * Intermittent parity check or other memory-type errors. * Hard disk and fan simultaneously failing to spin (no +12v). * Overheating due to fan failure. * Small brownouts cause the system to reset. * Electric shocks felt on the system case or connectors. * Slight static discharges disrupt system operation. In fact, just about any intermittent system problem can be caused by the power supply. I always suspect the supply when flaky system operation is a symptom. Of course, the following fairly obvious symptoms point right to the power supply as a possible cause: * System is completely dead (no fan, no cursor) * Smoke * Blown circuit breakers
Can you use a CR2025 3v battery in Pokemon emerald?
I'm not so sure..but give it a try..
What is voltage of cr2025?
3 volts.
What current does a torch carry using a 3 volt battery?
3v battery is used direct current
Can you recharge a 3V battery with 12V charger?
It is not recommended to recharge a 3V battery with a 12V charger as this may damage the battery. The voltage of the charger should match the voltage of the battery to avoid overcharging and potential safety hazards. It is best to use a charger specifically designed for the 3V battery.

How can you get a 3v cr2032 battery for your Pokewalker?
at the store
What battery used in sears craftsman garage door opener 139.53681B the 2032 3v or 2 2016 3v Manual says either or but 2 2016 would make 6v?
The difference between the two is the 2032 3v battery is just one battery per package. The 2016 3v are sold in packages of two. Therefore, the 2016 would mean you would have 2 batteries to use. One to replace the battery that has died and one to save as a back up or to put in a second remote for your garage door opener.
