What is the formula for calculating the voltage (in a system with a 4-20 mA current loop and a resistance (R) of 250 ohms?
A. V = I250
B. V = I4 + 250
C. V = I16
D. V = I20 – 4
Answer:C

Explanation: In a system with a 4-20 mA current loop and a resistance (R) of 250 ohms, the voltage (V) can be calculated using the formula V = I*16, where I is current in mA.
