Question 1 (9 marks) The circuit given in Fig. 1(a) uses a linear nonlinear capacitor having the q-v relations = volt. The triangular waveform v given in Fig. 1(b) is apP circuit elements. having resistance R = 500Q and a 2 where q is in coulomb and v is in| parallel combination of these two time-invariant resisto hip g = 0.005(v + 1); OD lied to the i; Vy ip 1 > 15 t(s) v{ 0 ! 0 5 10 Fig. 1(a) Fig. 1(b) (a) Express the voltage v as a function of tin the time interval 0 < t< 10. (q (b) Hence obtain an expression for the current / through the capacitor as a function of t. (4 (c) Hence calculate and sketch the waveforms of the currents /, and i, for 0 < t < T. 8.
