Need to find Current that crosses 10ohm resistance.
Im lost on how coils impact the equations.
Can someone write the eqs for the 2 branches, and xplain?

the 4 H inductor doesnt matter. just do a phasor transform

did the transform.
The eq for first branch is this ?

-100 + 10 IA + j25 IA + j15 IB = 0
correct?

why are you doing branches. just divide 100 by 10 + phasor transform of 5H

that will be the current through the 10 ohm resistor.

u sure you know what you're saying? I dont get this
you're saying the only voltage I need is the 100
There is also voltage at the center node that is impacting the current through 10ohm.

Can't you just use node voltage?

is there, like, a load across V+? otherwise that inductor is totally irrelevant rite?

Yeah i suppose that makes the voltage across the other inductor Vb.

-100 -j250 not -10 - j250 I can't divide

Actually this is completely wrong. Don't take advice from me OP

The source is in a superposition of state with the inductor. They are both entangled. The probability the voltage is an integer value is the uncertainty of the output impedance.

I took an E&M class, but we stopped at RC circuits (there was no magnetism either lol). Is it a good idea to go back and study the L/RL/RLC (inductor) circuits?

If there's no load then just take the impedance of the 5h inductor add to the resistor then divide by the voltage, no stress man.

This is just retarded wow.
>You know R(inductor) = omega * L
>Just calculate XL parallel
>I = V/R where instead of R you use Z which is R + JXL

Ez....?

The mutual inductance of 3H and the inductor coil of 4H are irrelevant to the current since no current can flow in the 4H coil. The 5H coil has an impedance of i25. The total impedance seen by the source is therefore 10 + i25. Covert this to a phasor, divide 100 by the result to get the current.

The voltage is a tougher question because the open circuited 4H coil can't produce a current but can produce a voltage, like an open circuited transformer.
