Hi Everyone,
This might be just a simple question.
When measuring voltage of a simple resistance serie with inductance(R--L) circuit. The scope was probed at the inductance.
When powering this circuit with DC power supply, voltage will rise rapidly almost to power supply voltage. With the setup I have, maximum voltage is about 80% of the power supply. And the risetime is about 100 nsec.
I wonder what is the parameter that control this rising time and maximum votage at initial startup. Is it scope probe or parasistic capacitance/resistance of the inductor?
Thanks,
KJ
