Electric Current Physics Example 1

Follow the full solution, then compare it with the other examples linked below.

Example 1

easy
A charge of 10 C10 \text{ C} flows through a wire in 5 s5 \text{ s}. What is the electric current?

Solution

  1. 1
    Use the current formula: I=QtI = \frac{Q}{t}.
  2. 2
    Substitute the given values: I=105I = \frac{10}{5}.
  3. 3
    I=2 AI = 2 \text{ A}

Answer

I=2 AI = 2 \text{ A}
Electric current is the rate of flow of electric charge. One ampere means one coulomb of charge passes a point per second.
