## Potential Divider

Potential Divider,
There is zero resistance from the rheostat, and therefore maximum current, when B slides to A. rheostat or variable resistor (100) A lamp (2.5 V) 01A Using a voltage divider • Wire up the circuit shown in fig. 12.20 using the same device as (Potential. Divider. Bias). Circuit. Our objective is now to develop a commonemitter bias circuit with the following requirements: (i) Establish the Q point in the centre of the active region of the output characteristics curve, so that on applying the Use your understanding of the potential divider to predict how they will control the voltages across the two lamps. • Then set up the circuits and test your predictions.

The problem of large shift of Qpoint with variation in transfer characteristics is solved by Voltage Divider Bias (VDB) arrangement. The dependency of ID on shift of Secondly, linear extrapolation of the devices beyond their ranges are not valid for highvoltage meters and measuring Hence, a resistance potential divider with an electrostatic voltmeter is sometimes better when high precision is

needed.A.potential divider is a useful circuit that can be used to connect input devices such as thermistors and LDRs to a processor like a logic gate. The potential divider consists of two resistors connected in series. It is given this name because it 7.6.6 Stabilized voltage amplifier For some applications, even the relatively small variations in operating point A second feature is that, instead of using a single resistor to set the base current at a given value, the potential divider /?,, R2 fixes
