How to convert 9v to 3V using resistor

R 1 = V s ∗ R 2 V o u t − R 2 = 9 V ∗ 1000 Ω 3.3 V − 1000 Ω = 1727 Ω. Using common resistor values, I can get to 1.69 K, which is close enough — unless you want a precise voltage reference, but we'll come back to that later There are basically two reasonable approaches to making 3.3 V and 5 V power from 9 V. These are a linear regulator and a buck converter . A linear regulator is like a self-adjusting series resistor Using a 9V source I can calculate R = (9v-3v)/(15mA+15mA) R = 6/0.03 = 200 Ohms I have 0.03^2 * 200 = 0.18W or 180mW for the resistor and the circuit will consume 3v * 0.015A = 0.045 or 45mW only.the resistor alone will consume 4 times more than the circuit This is the formula we can use for choosing the resistor value we need to get any voltage we want. So back to our circuit, if we have 5 volts and want 3V from it, we use the formula above. If we use a 10KΩ as our R 1 resistor, plugging in the values, we get R 2 = (V) (R 1 )/ (V IN - V)= (3V) (10KΩ)/ (5V - 3V)= 15KΩ

how to convert 20v dc to 3v dc using resistor? Yahoo Answer

First I measured the current used by my device, on the output side of the converter, which was around 50mA. I then I created a dummy load of 100 ohm using two 200 ohm resistors in parallel. I used a resistor array to reduce the load on each individual resistor which was rated for 0.25W I'm using MCP3008 to interface to the Raspberry Pi. The MCP Vdd is 3.3V and from the same source as Raspberry Pi. One of the analog inputs to the MCP is from a instrumentation amp (opamp) AD620. I've found for my circuit, operating the AD620 (using to interface to load cell) from a 5V works better than from a 3.3V Removing the 15kΩ resistors. And connecting the SDA and SCL through the new device. And of course connecting 5V to 5V and 3.3V to 3.3V. Then have Volt meter connected to SCL 3.3V and to ground as follows: When running the examples you should be measuring close to 3.3V here.

Thermistor - series resistor combination (voltage divider) A common way for microcontrollers to capture analog data is via an analog to digital converter (ADC). You can't directly read the thermistors resistance with an ADC. The series thermistor-resistor combination, shown in figure 4, provides a simple solution in the form of a voltage divider I created a simple circuit using the LM317 to output 3.3 volts from a 5V or greater input voltage. Why? Because, a number of modules for the Arduino (or Pinguino) take 3.3 Volts.It's true, some of the Arduinos do have a 3.3V voltage regulator (and thus a source of 3.3V), however, that might not have sufficient amperage

Let's use the example of us using a linear power supply of a 9V and we want 5V output. This is a power efficiency of, power efficiency= (power output/power ) * 100%= (5V/9V) * 100, which is a power efficiency of 55%. This means we are wasting 45% of the power supplied to the circuit. This is a huge waste if u use resistor to compensate some of the voltage, it will be unstable and the resistor will generate heat which is unnecessary for ur pc. same as the idea of using diode, because the voltage drop on the diode itself drift unevenly, hence u are not sure whether the output u get is exactly 3.3V or not. 2 Answers2. This device is and open collector sinking (see the datasheet). That mean that you need to connect a pull-up resistor on the output. So if you connect the output pull-up resistor to the Pi 3.3V and the output to the Pi GPIO it will work. If the device outputs a square wave (i.e. a digital signal) you should use a level converter

Using a voltage divider is just that bit more ridiculous. If you want roughly 9V, as someone already said you could use the 12V and 3.3V lines quite effectively. You could also build a regulator using the 12V and gnd wires, an LM317 regulator, and a few resistors and caps Until now I've just been using a MOSFET with 12v and a pulldown resistor connected to the gate, which then passes 3.3v to the teensy, but because of size requirements on the board I need to move to something much smaller, the problem is that the signal is a tail light signal in a car coming from a relay, meaning that the input is either 12v or open

Making 3.3V, 5V Voltage Regulator Circuit with Diodes and ..

This LED calculator will help you calculate the resistor values you will need when designing a series/parallel LED array circuit 5. Connect the Power-On LED to a 330 ohm resistor. Connect the cathode (short end) of the LED to the anode of one of the 330 ohm dropping resistors. Then connect the cathode of the dropping resistor to a black ground wire. Once the LED is connected, you can use hot glue or super glue to mount the LED in it's place 230v/220V AC To 12 V DC Regulated Power Circuit Diagram and 220v/230 AC to 5V DC Regulated Power Circuit diagram using Voltage Regulator . All Electronics Devices are operated using DC Power Supply. They Works Well and Protected By Regulated Voltage Supply. 12v DC Regulated Voltage Supply, full wave Bridge rectifier Guy is correct on a simple way to convert 12v to 9v. I also did this using LM317 adjustable voltage regulators (good for a little over an amp draw) as shown in THIS schematic for my Car Monitor How-To. Just look at the bottom part of that schematic. (I happened to already have a bunch of LM317's at the house) Resistor Power Rating = I F 2 x Resistor Value = (20mA) 2 x 200 Ω = 0.08 W = 80mW. But This is the minimum required resistor value to ensure that resistor will not overheat, so its recommended that to double the power rating of resistor that you have calculated, therefore, choose 1.28W x 2 = 2.56W resistor for this circuit. Resistor power rating (Value is doubled) = 2.56W (280 mW

Resistor R2 and capacitor Step Up Voltage Converter - This circuit is actually a 3Volt to 8Volt dc dc converter designed using IC LM 2700 which is a step up switching converter.In this particular circuit LM 2700 is wired to produce 8volts from 3 volts at a switching frequency of 600 Hz. 5. 3V to 5V Converter Circuit - This voltage. I'm using an analogue meter in series with the 2200mAH LiPo battery, set to its 250mA current range. I used an analogue meter because it responds quickly to changes and is accurate enough for this sort of testing. The variable resistor attached to via the orange and yellow wires, is to control the charge current on the TP4056 LiPo charger module i wonder if our group is using the correct value for resistor and capacitor for the low pass filter. 10k ohm and 3.2 nF respectively for a 5khz cut-off frequency. this application is for our project wireless communication based laser with certain distance to cover.. we are using a PIC 877A for a PWM output, then we decided to low pass filter the PWM output to generate analog waveform convert it into a single-ended signal. Such applications can be used to condition the signal (the resistors) and the op amp itself. The common mode rejection ratio (CMRR) the Vicm of the op amp is 9 V. Thus, if the op amp is supplied by 5 V, we canno Other direction-control techniques include using a microcontroller and driving the DE input with data while pulling the A-B lines apart (connecting a pull-up resistor from A to 5V and connecting a pull-down resistor from B to ground). The value of these resistors varies with cable capacitance, but is typically 1kΩ. Figure 9
