Consider the table above. It shows the potential difference across a resistor ( ) as a function of time in a charging RC-circuit. Suppose that the empirical equation which describes the data is given by:
, where
and
are constants.
Use the data in the table shown above and determine the value of the constant .
Note: use Excel to draw the graphs.
Beskou die tabel hierbo. Dit toon die potensiaalverskil oor die weerstand ( ) as funksie van tyd in ’n laai RC-stroombaan. Veronderstel dat die empiriese vergelyking wat die data beskryf gegee word deur
waar
en b konstantes is.
Gebruik die data in die tabel hierbo en bereken die waarde van die konstante .
Let op: maak gebruik van Excel om die grafieke te teken.
