A $\backslash (108\backslash$mu $\backslash$mathrm$\{$~F$\}\backslash )$ capacitor is connected to a source that operates at $70$ Hz with a peak potential difference of $14$ V $.$ Find:

a$)$ the peak current:

A

b$)$ the current when the potential difference has its peak value:

A

c$)$ the current when the potential difference has one$-$half the $($positive$)$ peak value $($there are two answers, list them in increasing order$)$:

A

A

d$)$ the instantaneous power delivered to the capacitor at $3$ ms $.$
