- \( 0.5(v_1 + v_2)(1 + \frac{R_2}{R_1}) \)
- \( (v_1 + v_2)(1 + \frac{R_2}{R_1}) \)
- \( 1.5(v_1 + v_2)(1 + \frac{R_2}{R_1}) \)
- \( 0.5(v_1 - v_2)(1 + \frac{R_2}{R_1}) \)
Show Solution
The Correct Option is A
Solution and Explanation
This circuit represents a differential amplifier. The output voltage, \(v_{\text{out}}\), is calculated based on the input voltages and resistor values using the following formula:\[v_{\text{out}} = 0.5(v_1 + v_2)\left(1 + \frac{R_2}{R_1}\right)\]
Final Answer: \[\boxed{0.5(v_1 + v_2)(1 + \frac{R_2}{R_1})}\]
Final Answer: \[\boxed{0.5(v_1 + v_2)(1 + \frac{R_2}{R_1})}\]
