In the circuit below, the voltage $V_L$ is ___________ V (rounded off to two decimal places). 
In the circuit below, the voltage $V_L$ is ______________ V (rounded off to two decimal places).} 
A sample and hold circuit is implemented using a resistive switch and a capacitor with a time constant of 1 $\mu$s. The time for the sampling switch to stay closed to charge a capacitor adequately to a full scale voltage of 1 V with 12-bit accuracy is ____________ $\mu$s (rounded off to two decimal places).
