Answer :
Answer:
The charge can be calculated using the formula:
\[ Q = I \times t \]
Where:
- \( Q \) is the charge in coulombs.
- \( I \) is the current in amperes.
- \( t \) is the time in seconds.
Given:
- Current (\( I \)) = 0.68 × 10^-4 A
- Time (\( t \)) = 3 seconds
Now, let's calculate the charge:
\[ Q = (0.68 \times 10^{-4}) \times 3 \]
\[ Q = 2.04 \times 10^{-4} \, \text{coulombs} \]
Therefore, the charge is \( 2.04 \times 10^{-4} \, \text{coulombs} \).
