A charge `0.5 C` passes through a cross section of a conductor in `5 s`. Find the current.

Answer

To find the current when a charge of 0.5 C passes through a cross-section of a conductor in 5 seconds, we can use the formula for electric current.

### Step-by-Step Solution:

1. **Understand the Formula for Current**:
The electric current (I) is defined as the rate of flow of charge. The formula is given by:
\[ I = \frac{\Delta Q}{\Delta T} \]
where:
- \(I\) is the current in amperes (A),
- \(\Delta Q\) is the charge in coulombs (C),
- \(\Delta T\) is the time in seconds (s).

2. **Identify the Given Values**:
From the problem, we have:
- \(\Delta Q = 0.5 \, \text{C}\) (the charge),
- \(\Delta T = 5 \, \text{s}\) (the time).

3. **Substitute the Values into the Formula**:
Now we can substitute the values of \(\Delta Q\) and \(\Delta T\) into the formula:
\[ I = \frac{0.5 \, \text{C}}{5 \, \text{s}} \]

4. **Calculate the Current**:
Performing the division:
\[ I = \frac{0.5}{5} = 0.1 \, \text{A} \]

5. **State the Final Answer**:
Therefore, the current is:
\[ I = 0.1 \, \text{A} \]
