I just joined the forum but have been using Origin for last one year mainly for plotting of data. This time I have some data of electric current over time. Current is varying with respect to time (interval of 10 msec). I 300 samples of current i.e. current is recorded for 3 seconds. Current looks like an exponentially decaying current. Similarly I have the voltage samples over the same amount of time.
I want to integrate the current and in fact I have integrated and it gives me an almost straight line with little curvature. I do not know how to interpret the y-axis value. x-axis is time. Can somebody explain it? Thanks for reading my problem. Images are given below for both current and its integral.
Current I is the amount of charge dQ transferred per unit time dt. In other words, I = dQ/dt. Your integral is the cummulative charge Q transferred from time = 0 to time = t. Label your y-axis "Charge (millicoulombs)".
