**Title: Calculating Circuit Current**

Calculate the current from Vs and the current going to Ground (bottom of the diagram) for the following circuit. Use the following parameters for the circuit: 

- Vs = 10 V
- R1 = 470 ohms
- Vf for D1 and D2 = 2.1 V
- R2 = 110 ohms

Show your calculations.

**Diagram Explanation:**

- The circuit diagram consists of a voltage source (Vs) at the top.
- There are two resistors: R1 and R2. R1 is positioned before any diodes, and R2 is after. 
- Two diodes, D1 and D2, are connected in series between the resistors.
- The circuit concludes with a ground connection at the bottom.

**Instructions for Calculation:**

To calculate the current through the circuit, consider these steps:

1. **Determine Total Voltage Drop Needed for Diodes:**
   - Each diode has a forward voltage (Vf) of 2.1 V.
   - Total Vf for both diodes = 2 * 2.1 V = 4.2 V.

2. **Calculate Voltage Drop Across Resistors:**
   - Vs provides 10 V.
   - Voltage left for R1 and R2 = Vs - Total Vf = 10 V - 4.2 V = 5.8 V.

3. **Calculate Total Resistance:**
   - Add R1 and R2: Total resistance (Rt) = R1 + R2 = 470 ohms + 110 ohms = 580 ohms.

4. **Use Ohm’s Law to Calculate Current (I):**
   - I = Voltage across resistors / Total resistance = 5.8 V / 580 ohms.

Through this process, students can find the current from Vs and the current flowing to the ground.
