We are taught that parallel circuits maintain equal voltage across all branch resistors, equally sharing the source voltage. But reality is often far from ideal, and individual devices certainly impact the rest of the circuit.
Industrial analog sensor devices primarily use 0-10 volt or 4-20 milliamp. For those mA signals, learn the reasons for…
Industrial analog sensor devices primarily use 0-10 volt or 4-20 milliamp. For those mA signals, learn the reasons for why the lower and upper limit standards were determined as 4 mA and 20 mA.
