What is the effect of increasing the loop resistance on a 4 to 20 mA transmitter?
A. The current through the transmitter increases
B. The voltage across the transmitter increases
C. The power consumption of the transmitter increases
D. The voltage drop across the loop resistance increases
Answer:D
What is the effect of increasing the loop resistance on a 4 to 20 mA transmitter?
A. The current through the transmitter increases B. The voltage across the transmitter increases C. The power consumption of the transmitter increases D. The voltage drop across the loop resistance increases
Explanation: Increasing the loop resistance on a 4 to 20 mA transmitter will increase the voltage drop across the loop resistance, which in turn will reduce the voltage available to the transmitter. This will cause the current through the transmitter to decrease, as the voltage available to drive the current is reduced.
