🔍 Key Concepts

• Common industrial control loop current ranges • Why a live-zero (non-zero minimum current)** is useful in instrumentation • Typical current levels that are safe for long cable runs without excessive voltage drop

💭 Think About

• Which option looks like a small, precise current suitable for sensors and transmitters rather than power equipment? • Think about why having zero signal correspond to a small but non-zero current can help detect a broken wire or loss of signal. • Eliminate any answers that use current levels more typical for power circuits rather than control signals.

✅ Before You Answer

• Rule out options measured in amperes (A) that would be unusually high for delicate instrumentation loops. • Focus on milliampere (mA) ranges that are widely used in process control and automation systems. • Consider which mA range is known for allowing easy fault detection when the signal drops below its minimum normal value.
