A charge of 25 C flows through a conductor in 10 s. Calculate the current.

Solution & explanation

1. Given: Q = 25 C; t = 10 s.

2. Find: Current I in amperes.

3. Current is charge transferred per unit time.

   $$I=\frac{Q}{t}$$

4. Substitute charge and time.

   $$I=\frac{25}{10}$$

5. Divide 25 by 10.

   $$I=2.5$$

6. State the result with units: I = 2.5 A.

I = 2.5 A
