Weband we have derived the voltage divider equation: The output voltage equals the input voltage scaled by a ratio of resistors: the bottom resistor divided by the sum of the resistors. The ratio of resistors is always less than 1 1 for any values of \text {R1} R1 and \text {R2} R2. WebSep 22, 2024 · Potentiometer Circuit Solution: Since the two resistance are in series, total resistance R = R 1 +R 2 = 200Ω. The current flowing through the circuit will be I = V/R =10/200 = 0.05A. Voltage drop across R 2 = 50Ω can be found by voltage division rule, that is V R2 = 10 × (50/200)= 2.5 V high pine whiskey yell
