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.
