I need to convert a Particle System to a mesh object, so I can export it to Unity 3D. How could I do this?


Question: Electric current of inductor
Answer: I would say that both answers are wrong. Imagine if the inductor were omitted from the circuit and any source of voltage or current were applied (via the 3 ohm series resistor) to what is basically a balanced bridge.

What would be the voltage at the junction of the two 1 ohm resistors - it would be the same voltage as at the junction of the two 3 ohm resistors - net voltage across the two points (where the inductor was connected) is always zero.

So, now replace the inductor and ask yourself what the net voltage across the inductor will be - it'll still be zero and never, ever will any current flow thru it.
