Answer the following statement true (T) or false (F)
Answer the following statement(s) true (T) or false (F)
1. The operational amplifier is often used as a level detector or comparator. 2. When the 741 op amp is used as an inverted amplifier, the zener diode produces a constant positive voltage at the noninverting input of an amplifier and is used as a reference. 3. As long as the noninverting input is more negative than the inverting input, the output of the amplifier will be high. 4. The advantage of the RTD is that it has a low temperature coefficient. 5. Schematic diagrams, in a universally accepted practice, point the arrow through a resistor toward the top of the circle to indicate the use of an RTD, and toward the bottom of the circle to indicate the use of a thermistor.
