What Are The Disadvantages Of Voltage Divider? One disadvantage with the voltage divider is that it is not possible to maximize ∆vOUT and at the same time minimize vOUT in the ambient condition, which would require R1 to be as large as possible and therefore result in a negligible voltage change in response to darkening.
How Do You Select Resistors For Voltage Divider? Here’s a very rough rule of thumb: The current flowing through the two resistors (assuming no input current) should be 10 to 1000 times more than the input current. The more current is flowing through these resistors, the less the input current will effect things. Does resistor
Does A Voltage Divider Affect Current? Does a voltage divider affect current? By selecting appropriate values of resistors in the divider, it is easy to obtain required output current from the divider. If you use 10 Ohms for R1 and 20 Ohms for R2, same output current of 5 mA will be produced but increased
