Assuming that the op-amp in the circuit shown below is ideal, the output voltage V₀ (in volts)

In the circuit shown, assume that the opamp is ideal. The bridge output voltage V₀ (in mV) for $$\delta = 0.05$$ is______.

The circuit shown in the figure has an ideal opamp. The oscillation frequency and the condition to sustain the oscillations, respectively, are

In the voltage regulator circuit shown in the figure, the op - amp is ideal. The BJT has V_BE = 0.7 V and $$\beta $$ = 100, and the Zener voltage is 4.7 V. For a regulated output of 9 V, the value of R (in $$\Omega $$) is ______
