**Circuit Analysis Problem**

The circuit problem involves a diode in the given configuration with key parameters provided for analysis:

1. The diode has a reverse-bias saturation current \( I_s = 10^{-15} \, \text{A} \).
2. The thermal voltage \( V_T = 26 \, \text{mV} \).
3. The ideality factor \( n = 2 \).
4. The current through the diode is specified as \( 2 \, \text{mA} \).

**Objectives:**

a) Determine the supply voltage \( V_s \).
b) Calculate the power dissipated in the diode.

**Circuit Diagram**

- The circuit includes:
  - A voltage source (\( 6 \, \text{V} \)) in series with a diode and a \( 3 \, \text{k}\Omega \) resistor.
  - The diode is oriented to allow current flow from the voltage source through the resistor.

**Analysis Instructions:**

- Use the diode equation and Ohm's law to solve for the unknown voltages and power dissipation.
- Consider the parameters given to evaluate the behavior of the circuit and arrive at the solutions required.
