The value of the resistor determines the voltage range that corresponds to the current range. For example, in a 4 to 20 mA system with a 250 ohm resistor, the voltage range is 1 to 5 V, because V = IR, where V is the voltage, I is the current, and R is the resistance. What is the value of resistance?
