Example 1: 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 = 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 Example 2: Find the voltage across a 2-uF capacitor and the energy stored if the current through it is given as below. Assume the initial voltage of the capacitor is zero. capacitor and sketch the current waveform i(t) = 6exp(- 300t)mA. Find the current if the voltage source is triangular.
