First post here... Sorry it has to be a question.

I'm currently studying electrical engineering at university. Anyway, I've hit a couple of these mesh type circuits in my workbook and have no idea how to tackle them?

The question asks to solve using Thevenin's Theorem, but they look completely different to our worked examples and I'm at a loss as to where to begin, let alone solve the questions!

2. Relevant equations

Here is one of the questions -

Given: E1 = 200 V;

R1 = 15 Ω; R2 = 20 Ω;

R3 = 20 Ω; R4 = 12 Ω

and RL = 27 Ω

(a) Use Thevinin’s theorem

to determine the value of

current I.

(b) Check you answer using

Δ-to-Y transformation

and Kirchhoff’s laws.

3. The attempt at a solution

Like I said, unfortunately I don't know where to begin with this

Thanks in advance to anyone who can help me out here.
