WebA resistor has scaling (and therefore automatically has additivity). A resistor is a linear element. For a real-world resistor there is of course a limit to the voltage and current. If the power (i\cdot v) (i ⋅v) is more than the resistor can handle, it may change resistance value as it … WebBasically, Ohms law is used to calculate a resistor value in order to convert the 4 to 20 mA to a voltage. The most popular resistor value for this purpose is 250Ω, since it will produce a 1 to 5 Vdc signal when 4 to 20 mA flows through it, and a 0 to 5 Vdc input is very common for most data acquisition systems and other analog measurement devices. flash大厅
