### Electrical Circuit Analysis

#### 1a) KCL, KVL, and Power

**Consider the circuit shown on the right which contains:**
- A 10V voltage source
- A 2A current source

The voltage across the current source is known to be 16V, as shown in the circuit diagram.

#### Questions:

**i) Carefully showing your workings, use Kirchhoff's Current Law (KCL) and Kirchhoff's Voltage Law (KVL) to find \( I_R \) and \( V_R \), and hence find the value of the resistance \( R \).**

**ii) Find the power absorbed by the voltage source.**

---

#### Circuit Diagram Explanation:

The provided circuit diagram contains a 10V voltage source and a 2A current source in series with a resistor \( R \). The key points of the diagram are:
- The voltage across the 2A current source is given as 16V.
- The voltage source and the current source are connected in series with the resistor \( R \).
- The labeled components are:
  - \( I_R \): The current through the resistor.
  - \( V_R \): The voltage across the resistor \( R \).
  - A 10V voltage source.
  - A 2A current source.

The circuit diagram visually aids in the application of KCL and KVL for solving the problem.

---

To solve these questions:

1. **Apply KCL and KVL:**
   - Apply KVL around the loop to find the unknowns.
   - Apply KCL at any nodes if necessary to understand current distribution.

2. **Calculate the Power Absorbed:**
   - Use the power formula involving voltage and current to determine the power absorbed by the voltage source.

By following these steps, students can grasp the fundamentals of circuit analysis using Kirchhoff's laws.
