Answer:

570 Coulombs

Explanation:

We are given;

  • Current drawn by the head lamp as 1.9 A
  • Time the charge flows through the bulb is 5.0 minutes

We are required to calculate the charge that flows through the bulb;

  • Using the formula;

Q = It

where, Q is charge in coulombs, I is the current and t is time in seconds.

In this case;

Time = 5.0 minutes

But, 1 min = 60 seconds

Time = 300 seconds

Thus;

Charge, Q = 1.9 A × 300 seconds

                  = 570 Coulombs

Hence, the charge through the bulb is 570 Coulombs
