A triangular voltage with waveform defined as follows: V=0 at t = 0, V = 50 at t= 1s, V = 0 at t = 2, V = -50 at t = 3, and V= 0 at t = 4 is applied to the terminals of e 200pF capacitor. Sketch the voltage waveform and derive an expression for the voltage signal. Find the current that flows through the capacitor and sketch the current waveform
