3.6 Study of the i(t) curves
We show (from the law of voltages) that in general:
=
( i ) t
With values of E and R known, it is possible to verify this relation for one of
the current curves: we construct, in the Calculations workshop of Généris 5,
the curve i(t) that we compare with the acquired curve i(t).
Similarly, from the acquisition of the voltage U
curve i obtained can be superimposed on the function:
5
( i =
) t
The two curves obtained for the C = 100 µF, R = 1000 Ω pairs are
represented above. The derivative U'
