If you know resistance, it is an easy calculation (with Ohm's Law) to convert volts into amps.

Take your voltage against time plot and change the values along the voltage axis. Where it says 2 Volts, change that to 2 Volts/R. For instance if your R=2ohms, change 2 Volts to 1 amp.Then you don't need to make any changes on the time axis and the original plotted line.

The graph is stated as a 'characteristic curve' in electronics. It us regularly occurring to place voltage on the x-axis and modern on the y-axis. The video under could help (from approximately 3mins 40secs). It explains a thank you to take the dimensions and the thank you to entice the graph.

Voltage = Current x Resistance
so if you have raw data in an excell file just divide each
voltage value by the corresponding resistance value then
plot it and walla.

You need the resistence value.
Volts = Amps (current) x Ohms (resistence)
If you have the Ohms value all you have to do is simple math to calculate Amps from Volts:
Amps = Volts / Ohms

It the voltage is time varying (not constant), you will need to know reactances in addition to resistance to determine current.

you would use an amp meter connected to the same recorder
via an adapter.
