The current shown below is drawn from a 20v source.  The waveform repeats every 0.2 seconds as shown.

A circuit representation for this situation is shown below.  The direction of current flow is out of the positive terminal (labelled "+") then through the element.

• Show the direction of current flow on the diagram.
• Determine how much charge flows through the element each period.
• Determine how much charge flows through the element each second.
• Determine how much work is done by the 20 volt source in each period and in a second.
• Determine the average power (averaged over one second or over one period) dissipated in the element.
