Question
In a non-inverting mode configuration of 741 op-amp, the feedback resistor is 10 kΩ, and the input resistor is 2 kΩ. If a 1V input signal is applied to the non-inverting terminal, what will be the output voltage of the op-amp?-6 V-10 V5 V6 V
Solution
The output voltage of an operational amplifier in non-inverting mode can be calculated using the formula:
Vout = Vin * (1 + Rf / Rin)
where: Vin is the input voltage, Rf is the feedback resistor, and Rin is the input resistor.
Given in the problem: Vin = 1V, Rf = 10 kΩ, and Rin = 2 kΩ.
Substituting these values into the formula, we get:
Vout = 1V * (1 + 10 kΩ / 2 kΩ) = 1V * (1 + 5) = 1V * 6 = 6V
So, the output voltage of the op-amp will be 6V.
