An AC power supply is connected to a capacitor of capacitance 7.5 uF. At time t=0 the power supply is switched on and starts providing a time-dependent voltage v(t)=V0cos(ωt) across the capacitor, where V0=5.3 V and ω=374 rad/s. The capacitor is initially uncharged. Part ( a) Find the current, in milliamperes with its sign, through the capacitor at time t=1.5 s.
