**Using a 0-5 Volt DC Analog Input to Read Other Signal Levels**

Z-121RH T-1 Dual Pin 3mm High Efficiency LED Red - Forward Voltage (DC) 2.0 Typical, 2.5 Maximum, Forward Current 20mA* Typical, 25mA* (*continuous duty rating). 16 …... If you hook a normal charger to it and get it to 13v+ and leave it for a while and then remove it to see what the voltage drops to, if it drops to 10v range, one cell probably bad, 8 volts – 2 cells are probably bad, etc… That is usually the case if the battery is just sitting there at those voltages.

**5 volts to the fuel pump at the plug. is there a fuel shutâ€¦**

So if we want 5 volts, we need at least 7 volts to maintain the steady 5 volts that we want. This power supply will not be able to convert from lower volts to 5. So …... 31/12/2009 · Look for one that will give 4.5 volts out and will allow the input to drop to within 0.5 volts of the output voltage (ie <5 volts). Don't get a LM317 as these need at least 6 volts to give 4.5 volts out so your output would drop each time the sun went behind a cloud.

**pic How to drop 6 volts to 5 volts - Electrical**

At 5 volts input, the 250 ? (precision) resistor will have 5 volts applied across it, resulting in 20 mA of current in the large loop circuit (with R load). It does not matter what resistance value R load is, or how much wire resistance is present in that large loop, so long as the op-amp has a high enough power supply voltage to output the voltage necessary to get 20 mA flowing through R load .... Volts and amps are related according to Ohm's law where volts are equal to amps multiplied by resistance. Amps alone won't tell you how much voltage you have. 2.5 amps could have 1 volt or 200 volts it will depend on how much resistance the 2.5 amps sees.

## How To Get 2.5 Volts From 5 Volts

### The volt Energy is measured in joules and so we need to know the connection between volts and joules. The potential difference (p.d.) between two points in a circuit is 1 V if 1 joule of electrical energy is changed to other forms of energy when 1 C passes from one point to the other.

- The sensors that work from this 5 volt reference signal modify the voltage and the computer notes the difference between the 5 volts it sends out and teh amount coming back in the signal circuit to be able to know what is happening in the engine. In the case of the MAP sensor, it is measuring engine vacuum in the intake manifold; the computer uses this signal to be able to know how much load
- 2/01/2013 · I make a Voltage Regulator Circuit. These are handy in solar applications where you need to power small 5,6,9 volt devices, so you can run them more efficiently directly off of you battery and not
- Calculate the resistance in ohms of a resistor when the voltage is 5 volts and the power is 2 watts. The resistance R is equal to square of 5 volts divided by 2 watts, which is equal to 12.5 ohms.
- A 3.0 Ohm coil around 5 Volts You may need more as you go down in ohms or up in # of coils. Here is another great chart for you to take a look at: Vaping Power Chart 2.0
