Q1
A microfluidic sensor uses a voltage divider with two resistors in series ($R_1=1\ \text{k}\Omega$, $R_2=9\ \text{k}\Omega$) powered by $V=5\ \text{V}$. A small capacitor ($C=100\ \text{nF}$) is placed in parallel with $R_2$ to filter noise. Which statement best describes the behavior of the circuit immediately after a step increase in the supply voltage?
