The two resistor voltage divider is used often to supply a voltage different from that of an available battery or power supply. In application the output voltage depends upon the resistance of the load it drives.

What is the purpose of a variable?
A variable resistor is used in cicuits to vary the current passing through the resistor. It is commonly used to change the value of current across a circuit, or to act as a voltage divider. They are commonly equiped with a knob outside of a cabinet, to enable the user to adjust the operation of a circuit, like a volume control on a radio or amplifier.
What are three important characteristics of electric circuit?
Voltage, frequency, current, impedance, and what the circuit is supposed to do are all important.
What is an 7805 regulator?
7805is a voltage regulator integrated circuit. It is a member of 78xx series of fixed linear voltage regulator ICs. The voltage source in a circuit may have fluctuations and would not give the fixed voltage output. The voltage regulator IC maintains the output voltage at a constant value. The xx in 78xx indicates the fixed output voltage it is designed to provide. 7805 provides +5V regulated power supply. Capacitors of suitable values can be connected at input and output pins depending upon the respective voltage levels.Pin Diagram:Pin Description:Pin NoFunctionName1Input voltage (5V-18V)Input2Ground (0V)Ground3Regulated output; 5V (4.8V-5.2V)Output
Where can one purchase cheap room divider partitions?
One can find 'Every Day Low Prices' at Walmart when purchasing a cheap room divider partition. One can also find inexpensive (cheap) room divider partitions on the Amazon website.
What purpose might the multimeter serve in maintaining and troobleshooting a computer network?
With the multimeter you can measure the voltage on parts of the circuit board. You can also measure the resistance of resistors and make sure there are no short circuits in the circuit.
How does a voltage divider work?
The essential circuit of a voltage divider, also called a potential divider, is:
What is a voltage divider circuit?
The voltage divider circuit is a network of two or more components in series, often resistors, between a potential difference. The voltage between the components will be somewhere between the potential difference across the whole network and so divides the total voltage into one or more intermediate voltages.
What is the voltage divider theorem?
it is aa linear circuit that produces the output voltage from the fraction of its input. It is also known as potential divider.
What is the difference between a voltage divider circuit and voltage regulator I was told if the circuit consumes low current then the voltage divider can be used what does that mean?
A: that is true for less current a divider is OK it has to do with the series resistance and loading if the loading is forever fixed and the source is also fixed at a value then a divider can be used no matter what the current is.
What kind of circuit lowers voltage?
you can use a voltage divider or a step-down transformer to lower voltage.
What happens to voltage in a parallel circuit?
Voltage can be divided by a voltage divider, also known as a potential divider. Scroll down to related links and look at "Calculations:voltage divider (potentiometer) - damping pad - loaded and open circuit (unloaded) - voltage drop at the voltage divider"
What are the application of voltage divider biasing?
To get reasonable gain without losing stability of circuit. ANSWER: Is to reduce the input to a lesser value or to match signals impedance
What is example of dependent source and independent source of voltage and current?
Boss its a circuit not a device, you can also create one of yours..... just use simple logic of voltage divider and current divider rules...-satendra.svnit@gmail.com
If all the resistors in a voltage divider circuit are doubled the output voltage will be half?
No, the output will remain constant. If you double all the values, the divider ratio will not change, and it is the ratio that determines the output voltage. The current flow through the divider itself will change, it will be half the original value. This could affect the accuracy of the divider. For the same accuracy, the minimum load resistance would be double the original value.
What is the voltage d?
voltage divider
What is the difference between voltage divider and potential divider?
its the same
What could be the tendencies for the voltmeter if the voltages to be measured exceed the range?
You'd potentially damage the meter. Whether you do or not is immaterial; if the meter cannot measure the range of voltages you are expecting, it will not give accurate readings over that voltage range, thus you should not use it. Buy a different meter that will measure over that voltage range, or use a voltage divider circuit to get a lower voltage at a certain ratio of what is actually in the circuit (this may be difficult to do, or very simple depending on the circuit tested - the key is you do not want to load the circuit with the voltage divider network).
