Inductive noise may be inducing voltage on the input circuit. WebBy adding a 120-ohm resistor at the end of an RS485 transmission line, the signal will be dampened by the resistor instead of reflected into the bus. If the value of the resistor does not match the characteristic impedance of the cable, reflection may occur. In most RS485 configurations, two termination resistors are used. baker ranch dental spaWebApr 27, 2024 · 2 Answers. Assuming that by "ideal coil" you refer to a purely inductive coil with an ohmic resistance R = 0, you can assume that, for the purposes of calculating total resistance, the coil is simply a short-circuit that bypasses the resistor in parallel. Computing the parallel resistance gives R (parallel) = 0, which is indeed what you arrived at! baker ranch map
