Your assignment consists of three circuit analysis questions:

1. Find $V_A$ and $V_B$ for a given circuit.
2. Determine the currents in an unbalanced bridge circuit and also find:
   • The potential difference across BD.
   • The resistance from B to D.
3. Find the branch currents in a network where each branch resistance is 1 ohm.

To solve these, I'll need the circuit diagrams. If your file contains the figures, you can either upload clearer images of the circuits or describe them so I can guide you through the calculations. Let me know how you'd like to proceed!

Meanwhile, here are some related questions that expand on your assignment:

1. What methods are best for analyzing unbalanced bridge circuits?
2. How can Kirchhoff’s Voltage Law (KVL) and Kirchhoff’s Current Law (KCL) help in solving complex circuits?
3. What is Thevenin’s theorem, and how can it simplify circuit analysis?
4. How do you calculate equivalent resistance in a mixed series-parallel circuit?
5. What is the significance of node voltage analysis in electrical circuits?

Tip:

For unbalanced bridge circuits, Wheatstone Bridge principles do not apply, so you’ll need to use Kirchhoff’s Laws or mesh/nodal analysis to determine unknown values.
