A Short Note on the Growth of Current in an RL d.c. Circuit


Click the switch to close or open it.

The resistance of the rheostat and the inductance of the inductor can be changed. Note that the change can only be made when the switch is open.

The values of the two knobs of the CRO can also be changed. The change can only be made when the switch is open.

 

Use of the Y-gain: Volts/Div and the time sweep: sec/Div

 

The polarities of the induced emf in the inductor are shown in the conventional colors: red(+), black(-).
