What is the formula for calculating the resistance (R) in a system with a 4-20 mA current loop and a voltage (of 24 V?
A. R = (V – 4)/0.02
B. R = (V – 20)/0.02
C. R = V/0.02
D. R = (V – 24)/0.02
Answer:C
What is the formula for calculating the resistance (R) in a system with a 4-20 mA current loop and a voltage (of 24 V?
A. R = (V – 4)/0.02 B. R = (V – 20)/0.02 C. R = V/0.02 D. R = (V – 24)/0.02
Explanation: In a system with a 4-20 mA current loop and a voltage (V) of 24 V, the resistance (R) can be calculated using the formula R = V/0.02, where 0.02 is current in A (20 mA).
