## Voltage divider Hi, May i know what is formula to calculate the voltage divider for this circuit ? by ashrof January 13, 2023 It is NOT a voltage divider. To be a voltage divider, the same current should flow through the two resistors. Here, some current from R1 is allowed to escape toward R5. The equations can be: Loop through V1: 3 = iR1 R1 + iR3R3 Loop through V2: 1 = iR4 R4 + iR5R5 Loop through R2, cable without resistor, R5, ground: 0 = -iR2R2 + iR5 R5 (The - sign is needed since we travel the loop backward across R3) And the fourth equation is supplied by the sum of current at the nodes with the wire without resistor: iR1 - iR3 = iwire = iR5 - iR4 Solve 4 equations with 4 unknowns. iwire has to be zero for the voltage divider formula to be applicable. (or close to 0 to get an good approximation, as when it is 10 000 less than iR1). by vanderghast January 13, 2023 Thanks by ashrof January 13, 2023 Add comment...
