Hi there! I have great problem in tackling some problems on this topic, I hope you can help me. 1. For a V-t graph, it has the shape of a sine curve but well beyond the x-axis. It has 3 complete cycle in 6ms as shown in the graph. Notes: V is the potential difference applied between the terminals in a circuit varies with time t. a. Sketch a graph of how the charge on the capactior changes over 6ms. I sketch it the same as the V-t graph, since Charge (Q) = CV.....Q is proportional to V. Am I right? b. Sketch a graph of the current in this circuit, marking clearly on this graph the I=0 value. I have thought of it for quite a long time, but can't figure it out yet.. I have attached the document which have the graph.
