# Finding voltage and current expressions (capacitance)

## Homework Statement

The charge on a 2-microfarad capacitor is given by q(t)=10^-6 * sin(10^5*t) C find the dexpression for the voltage and current?

## The Attempt at a Solution

the answer is v(t)=0.5sin(10^5t) , i(t)=0.1cos(10^5t) i dont get how they found the answer

Note that q = Cv and i = $\frac{dq}{dt}$.
