Question

An AC power supply is connected to a capacitor of capacitance
3.5 μF. At time *t* = 0 the power supply is switched on and
starts providing a time-dependent voltage *v*(*t*) =
*V*_{0} cos(*ωt*) across the capacitor, where
*V*_{0} = 4.1 V and *ω* = 372 rad/s. The
capacitor is initially uncharged.

A)Find the current, in milliamperes with its sign, through the
capacitor at time *t* = 2.5 s.

B)Calculate the voltage across the capacitor, in volts with its
sign, at time *t* = 2.5 s.

C)What is the magnitude of the maximum current through the capacitor, in milliamperes?

Please show all work and steps please! (:
