... These two can be replaced with a 1 kΩ resistor. The 1 and 3 kΩ resistors are in series because the same current flows through them. Add their resistances to find the equivalent 4 kΩ resistor. The 4 and 2 kΩ resistors are in series. The equivalent resistance is 4 + 2 = 6kΩ. Here we know that the 4 an ...

... keeping the voltage across R2 approximately constant when vC2 varies. This is done using the bootstrap method. When vC2=1/3Vcc, D is in on state and C3 is charging with 10V (2/3Vcc). When vC2 starts to increase, D goes in off state and vC3 remains approximately constant, 2/3Vcc. The I2 current is, ...

Potentiometer
A potentiometer /pɵˌtɛnʃiˈɒmɨtər/, informally a pot, is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name.Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment. Potentiometers operated by a mechanism can be used as position transducers, for example, in a joystick. Potentiometers are rarely used to directly control significant power (more than a watt), since the power dissipated in the potentiometer would be comparable to the power in the controlled load.
