In electronics, a voltage divider (also known as a potential divider) is a passive linear circuit that produces an output voltage (V out) that is a fraction of its input voltage (V in). Voltage division is the result of distributing the input voltage among the components of the divider. A simple example of a voltage divider is two resistors connected in series, with the input voltage applied
The voltage division rule (voltage divider) is a simple rule which can be used in solving circuits to simplify the solution. Applying the voltage division rule can also solve simple circuits thoroughly.
A voltage divider consists of two resistances R1 and R2 connected in series across a supply Voltage Vs. The supply Voltage is divided up between the two resistances to give an output Voltage Vo which is the Voltage across R2.
The Voltage Divider Rule. What is the voltage divider rule? The voltage divider rule is a simple way of determining the output voltage across one of two impedances connected in series.
Determine voltage across and using voltage division rule. Assume that , , , and Solution: Please note that the voltage division rule cannot be directly applied. This is to say that: The reason is that some current of is passing through and branch. If the branch was broken at some point, for example as: we […]
Current divider. A general formula for the current I X in a resistor R X that is in parallel with a combination of other resistors of total resistance R T is (see Figure 1): = + where I T is the total current entering the combined network of R X in parallel with R T.Notice that when R T is composed of a parallel combination of resistors, say R 1, R 2, etc., then the reciprocal of each
Current and Voltage in resistor networks using Ohms Law to find unknown values in Series and Parallel resistor circuits and finding the voltage across any resistor in a potential divider.
This is an article by Joe Guilbeau on alternators & alternator theory for those used in our FSJ's. (Depending on your connection speed, this may take a short while to load due to the number of graphics in the page). 10/28/2010 Version 17 rev. 1
Following on from the FTDI + ESP8266 post, if you do not have a FTDI serial adaptor you can use an Arduino. Here is how to set up the Arduino to talk to the ESP8266. I an using a 5V Arduino Nano which of course is 5V. The Esp8266 is a 3.3v device and so I am using a voltage divider to bring the Arduinos 5V down to 3.3v.
The RF Probe is one of the handiest accessories you can have around the shack. Using only 3 electronic components, it may rank as one of the simplest and cheapest homebrew projects.
