In the circuit, shown in the figure, the MOSFET is operating in the saturation zone. The characteristics of the MOSFET is given by $I_D=\frac{1}{2}{\left(V_{GS}-1\right)}^{2}mA,$ where V${}_{GS}$ is in V. If V${}_S$ = +5 V, then the value of R${}_S$ in kΩ is _________.

The two-input voltage multiplier, shown in the figure has a scaling factor of 1 and produces voltage output. If V₁ = +15 V and V₂ = +3V, the value of the V₀ in volt is ____.

The two inputs A and B are connected to a NOR based R-S latch, via two AND gates as shown in the figure. If A = 1 and B = 0, the output QQ̅ is

The circuit of a Schmitt trigger is shown in the figure. The Zener-diode combination maintains the output between ± 7 V. The width of the hysteresis band is ___________ V.

When the voltage across a battery is measured using a d.c. potentiometer, the reading shows 1.08 V. But when the same voltage is measured using a Permanent Magnet Moving Coil (PMMC) voltmeter, the voltmeter reading shows 0.99 V. If the resistance of the voltmeter is 1100 Ω, the internal resistance of the battery, in Ω, is _________.
