Question 3: One AC sine voltage is described by the expression:

v(t) = 12 sin (62.8 × t) [V]

a/ Calculate the peak-to-peak voltage Vpp, the frequency f and the

period T of the sine.

b/ When this ac sine voltage is applied on the capacitance C = 20uF,

write the current ic(t) on this capacitor as of a sine function.
