Variable Resistor: Basics, Application Circuits＆Common …

Potentiometers are rarely used to directly control significant amounts of power (more than a watt or so). Instead they are used to adjust the level of analog signals (for example volume controls audio equipment), and as control inputs for electronic circuits. For example, a light dimmer uses a potentiometer to control the switching of a TRIAC and so indirectly to control the brightness of lamps. WebEquation V out = V in ∗ R2 R1 + R2 V o u t = V i n ∗ R 2 R 1 + R 2 Where: V out V o u t = Output voltage. This is the scaled down voltage. V in V i n = Input voltage. R1 R 1 and R2 R 2 = Resistor values. The ratio R2 R1 + R2 R 2 R 1 + R 2 determines the scale factor. Applications farnborough odeonWebRead more: Current Density Formula.
