WebThis equation is specific to the voltage (V) across the resistance (R in ohms) being generated as a result of the resistance and current (I in amps) circulating through the resistance. As an example, a current shunt with resistance of 0.002 ohms and current of 30 Amps will result in the generation of 0.002 x 30 = 0.06 volts or 60 mV (milliVolts). WebEars.
