circuits analysis professor put 2 graphs on the board, one representing charge with respect to time and one representing current with respect to time. From what I understand, a charge is a collection of electrons and they move through the circuit, and the current gauges the amount of charge/electrons that passes by every second. Please clarify if this is correct. On the charge profile graph, I do not understand how the charge is fluctuating up and down to make a current since current is the change in charge over time. How does the amount of electrons/charge change within the circuit?
