I'm new to circuit analysis and I'm stuck on this question. My question is: What could I do, or what steps should I take to solve this kind of circuit?
What the question asks is basically the current going through resistor $R_2$, using nodal current analysis just gives me a bunch of equations and I can't use voltage analysis, finally I tried to do the equivalent resistance using the Wye-Delta transformation of the circuit and find that overall node is subject to a voltage of $45 \;\text{V}$ but what do I do with that?
