Sure, I'd be happy to provide some tips and advice for solving circuit analysis problems. Here are a few steps you can follow to approach the first question:

1. Understand the problem: Start by carefully reading and understanding the given question. Make sure you know what is being asked and what information is provided.

2. Draw a circuit diagram: It's always helpful to draw a clear and accurate diagram of the circuit. This will help you visualize the problem and identify the different components and their connections.

3. Apply Kirchhoff's laws: Kirchhoff's laws are fundamental principles used in circuit analysis. The first law, also known as Kirchhoff's current law, states that the sum of currents entering and leaving a node must be equal to zero. The second law, or Kirchhoff's voltage law, states that the sum of voltage drops in a closed loop must be equal to the applied voltage. Use these laws to write equations and solve for unknown values.

4. Use Ohm's law: Ohm's law states that the current through a conductor is directly proportional to the voltage and inversely proportional to the resistance. You can use this law to calculate the current, voltage, or resistance in a circuit.

5. Apply other relevant laws and equations: Depending on the complexity of the circuit, you may need to use other laws and equations such as Thevenin's theorem, Norton's theorem, or superposition to solve the problem.

6. Simplify the circuit: Sometimes, it can be helpful to simplify the circuit by combining resistors in series or parallel. This can make the calculations easier and give you a better understanding of the circuit.

7. Check your answer: Once you have solved the problem, make sure to double-check your answer using the given values and equations. This will help you catch any mistakes and ensure that your answer is correct.

Remember, practice makes perfect when it comes to circuit analysis. So, don't get discouraged if you encounter difficulties at first. Keep following these steps and with time, you'll become more proficient at solving circuit analysis problems. Good luck!
