**Question:**

For the circuit shown below, what is the total current in the circuit? (The voltage supplied to the circuit is V = 10.0 Volts)

**Circuit Description:**

- The circuit consists of four resistors:
  - \( R_1 = 10 \, \Omega \)
  - \( R_2 = 20 \, \Omega \)
  - \( R_3 = 20 \, \Omega \)
  - \( R_4 = 30 \, \Omega \)

- The resistors \( R_2 \) and \( R_3 \) are connected in parallel.
- This parallel combination is in series with \( R_1 \) and \( R_4 \).

**Answer Choices:**

- \( \, 1.3 \, \text{A} \)
- \( \, 10 \, \text{A} \)
- \( \, 20 \, \text{A} \)
- \( \, 0.2 \, \text{A} \)

**Explanation:**

To find the total current, calculate the equivalent resistance of the circuit and apply Ohm's Law:

1. Calculate the equivalent resistance of \( R_2 \) and \( R_3 \) in parallel:
   \[
   \frac{1}{R_{\text{parallel}}} = \frac{1}{R_2} + \frac{1}{R_3} = \frac{1}{20} + \frac{1}{20} = \frac{2}{20} = \frac{1}{10}
   \]
   \[
   R_{\text{parallel}} = 10 \, \Omega
   \]

2. Calculate the total resistance of the circuit:
   \[
   R_{\text{total}} = R_1 + R_{\text{parallel}} + R_4 = 10 + 10 + 30 = 50 \, \Omega
   \]

3. Apply Ohm’s Law to find the current:
   \[
   I = \frac{V}{R_{\text{total}}} = \frac{10}{50} = 0.2 \, \text{A}
   \]

**Correct Answer: \(\, 0.2 \, \text{A} \)**
