Options

A. 0.03 A
B. 0.3 A
C. 0.003 A
D. ЗА

Explanation

To find the current in the wire when a charge of 20 C flows for 2 hours, we can use the formula for current:

### Step-by-Step Solution:

1. **Identify the given values:**
- Charge (Q) = 20 C (coulombs)
- Time (t) = 2 hours

2. **Convert time from hours to seconds:**
- Since 1 hour = 3600 seconds, we can convert 2 hours to seconds:
\[ t = 2 \text{ hours} \times 3600 \text{ seconds/hour} = 7200 \text{ seconds} \]

3. **Use the formula for current:**
- The formula for current (I) is given by:
\[ I = \frac{Q}{t} \]
- Substituting the values we have:
\[ I = \frac{20 \text{ C}}{7200 \text{ s}} \]

4. **Calculate the current:**
- Performing the division:
\[ I = \frac{20}{7200} = \frac{1}{360} \text{ A} \]

5. **Convert to a decimal:**
- To find the decimal value of \(\frac{1}{360}\):
\[ I \approx 0.002777 \text{ A} \]
- Rounding this to three decimal places gives:
\[ I \approx 0.003 \text{ A} \]

6. **Conclusion:**
- The current in the wire is approximately 0.003 A.

### Final Answer:
The current in the wire is **0.003 A**.
