How do you calculate amps from voltage
WebFeb 2, 2024 · With Ohm's and Watt's equations you can calculate four variables - power, voltage, resistance and current. If you know the values of two of these variables, you can transform the above equations according to your needs. Underneath we list all of these transformations: Resistance: R = V / I; R = V² / P; R = P / I²; Current: I = V / R; I = P ... WebCurrent noise of the op-amp, which interacts with the resistors to produce a voltage noise; So first, you want to find the equivalent resistance seen from the inputs of the op-amp looking outward into the circuit, with voltage sources (such as the op-amp output) set to 0 V (equivalent to converting them to short-circuits to ground).
