The value of for which the gain in the circuit below is 8 will be (op-amp is ideal)

Assume one ideal op-amp, find V₀

If V₁ = 5 sin 20t – 0.01 sin 2000t (V)

V₂ = 5 sin 20t + 0.01 sin 2000t (V)

The voltage gain of the op-amp V₀/V_in is When R_variable = (1 – 3) kΩ

The input signal v_i to an op-amp 0.04sin(1.13 × 10⁵ t)V is to be amplified to the maximum extent. How much maximum gain can be had by using op-amp with slew rate 0.6 V/μsec

In the ideal circuit shown in figure, the value of load current I_L is___(mA).

[If 2R₁ = 2R₂ = R₃ + R₄] and R₄ – R₁ = 500Ω]

The circuit shown in figure uses an ideal op-amp. The maximum allowed value of R_L for the output voltage to be not lower than –13V is ___kΩ.
