WebFeb 22, 2010 · The voltage across the resistors will be equal to the sum of voltages across each resistor. Here is a figure of resistors connected in series. Three resistors R 1, R 2, and R 3 are connected in series. The total resistance R total is given by. Rtotal = R1 + R2 + R3. WebNov 19, 2024 · The working principle of the braking resistor is, that a braking resistor helps to stop or slow down a motor by dissipating surplus voltage produced by the decelerating electric motor. This dissipated energy can be handled by the resistor to ensure that the increased voltage is kept to secure levels to avoid damage to the drive.
