In the given black box unknown emf sources and unk

Question

In the given black box unknown emf sources and unknown resistances are connected by an unknown method such that (1). When terminals of 10 ohm resistances are connected to box then 1 A current flows and (2). when 18 ohm resistances are connected then 0.6A current flows then for what value of resistance does 0.1 A current flows?

Arun · Accepted Answer

If the Black box contains resistor with any other element in parallel, we have the value of current Non-zero at t=0. Thus, Black box contains circuit elements in series. If the Black box contains a resistor and a capacitor, then the initial current is Non-zero However, if the Black box contains a resistor and an inductor, then the initial current is zero and it saturates
