Question

Express \(v_{\text{out}}\) in terms of \(v_{\text{in}}\) for the given circuit, assuming the op-amp is ideal.

• A. \( 1.2 v_{\text{in}} \)
• B. \( v_{\text{in}} \)
• C. \( 0.5 v_{\text{in}} \)
• D. \( 4.0 \)

Hint:

In non-inverting op-amp circuits, \(v_{\text{out}}\) depends on the feedback resistor ratio.

Answer 1

The Correct Option is A

For an ideal op-amp in a non-inverting configuration: \[ v_{\text{out}} = \left( 1 + \frac{R_L}{R_{\text{in}}} \right) v_{\text{in}} = 1.2 v_{\text{in}} \]
Final Answer: \[ \boxed{1.2 v_{\text{in}}} \]
