The two input terminals of an op amp are labeled as:
- (a) high and low.
- (b) positive and negative.
- (c) inverting and noninverting.
- (d) differential and nondifferential.
Find the correct option, which provides the two terminals of an op amp.
Answer to Problem 1RQ
The option is (c) inverting and noninverting.
Explanation of Solution
Calculation:
Operational amplifier (Op amp):
An active circuit element, which consists of complex arrangement of transistors, resistors, capacitors and diodes to perform various operations, is known as operational amplifier.
The general electronic symbol of op amp is shown in Figure 1.
In Figure 1, the op amp has two inputs and one output. Two input terminals are named as inverting input and noninverting input terminals.
The inputs marked with the notations
Therefore, the option (c) is correct and the options (a), (b), (d) are incorrect.
Conclusion:
Thus, the correct option is (c) inverting and noninverting.
