Question
A circuit using an ideal OP-AMP is shown in the Figure.
Which of the following options gives the correct value of the current ?
Which of the following options gives the correct value of the current ?
Correct answer
(C) 3.0 mA
Solution
The non-inverting input is grounded, so the inverting input is a virtual ground (0 V) and draws no current.
- Current through the input 1 k: mA, towards the inverting node.
- This same 2 mA flows through the feedback 1 k to the right-hand node , so V.
- The 2 k from to ground carries mA from ground into .
