Question: Using the same parameter for the 741 op amp in Example 5.1, find vo in the op amp circuit of Fig. 5.45. Example 5.1 A
Using the same parameter for the 741 op amp in Example 5.1, find vo in the op amp circuit of Fig. 5.45.

Example 5.1
A 741 op amp has an open-loop voltage gain of 2×105, input resistance of 2 MΩ, and output resistance of 50Ω. The op amp is used in the circuit of Fig. 5.6(a). Find the closed-loop gain vo/vs. Determine current i when vs = 2 V.
