assistant: Given:

- Supply voltage \( V = 16V \)
- \( R_1 = 11 \, \Omega \) (series)
- \( R_2 = 14 \, \Omega \)
- \( R_3 = 3 \, \Omega \) (R2 and R3 in parallel)

---

### Step 1: Calculate equivalent resistance of \( R_2 \) and \( R_3 \) in parallel

\[
\frac{1}{R_{23}} = \frac{1}{14} + \frac{1}{3} \approx 0.07143 + 0.33333 = 0.40476
\]

\[
R_{23} = \frac{1}{0.40476} \approx 2.47 \, \Omega
\]

---

### Step 2: Calculate total resistance

\[
R_{\text{total}} = R_1 + R_{23} = 11 + 2.47 = 13.47 \, \Omega
\]

---

### Step 3: Calculate total current \( I \) in the circuit (same through \( R_1 \))

\[
I = \frac{V}{R_{\text{total}}} = \frac{16V}{13.47 \, \Omega} \approx 1.19 \, A
\]

---

### Step 4: Calculate voltage drop across the parallel branch \( R_{23} \)

\[
V_{R_{23}} = I \times R_{23} = 1.19 \times 2.47 = 2.94 \, V
\]

---

### Step 5: Calculate current through \( R_2 \)

\[
I_{R_2} = \frac{V_{R_{23}}}{R_2} = \frac{2.94V}{14 \, \Omega} \approx 0.21 \, A
\]

---

### Final answer:  
The current through \( R_2 \) is approximately **0.21 A**.
