In the circuit given below, what should be the value of the resistance \(R\) for maximum dissipation of power in \(R\)?

In the circuit shown below, it is observed that the amplitude of the voltage across the resistor is the same as the amplitude of the source voltage. What is the angular frequency \(\omega_0\) (in rad/s)?

In the circuit below, the two DC voltage sources have voltages of value \(V_1\) and \(V_2\). The expression for the power dissipated in the \(60\,\text{k}\Omega\) resistor is proportional to ____________________.

In the following circuit, the switch \(S\) is open for \(t<0\) and closed for \(t\ge 0\). What is the steady state voltage (in Volts) across the capacitor when the switch is closed? (Round off the answer to one decimal place.)

In the circuit shown below, the amplitudes of the voltage across the resistor and the capacitor are equal. What is the value of the angular frequency \(\omega_0\) (in rad/s)? (Round off the answer to one decimal place.)

In the following circuit with an ideal operational amplifier, the capacitance of the parallel plate capacitor \(C\) is given by the expression \(C=\left(\dfrac{\varepsilon A}{x}\right)\), where \(\varepsilon\) is the dielectric constant of the medium between the capacitor plates, and \(A\) is the cross-sectional area. In the above relation, \(x\) is the separation between the two parallel plates, given by \(x=x_0+kt\), where \(t\) is time; \(x_0\) and \(k\) are positive non-zero constants. If the input voltage \(v_i\) is constant, then the output voltage \(v_0\) is given by __________________.
