The current passing through a circuit if it takes 1 minute for 45C of charge to pass a point is 0.75A.

HOW TO CALCULATE CHARGE:

  • The charge of a circuit can be calculated by using the following formula:

  • Q = It

Where;

  1. Q = charge of circuit (coloumbs)
  2. I = current (amperes)
  3. t = time (seconds)

  • According to this question, it takes 1 minute for 45 C of charge to pass a point in an electric circuit. The current is calculated as follows:

  • 45 = I × 60

  • 45 = 60I

  • I = 45 ÷ 60

  • I = 0.75A

  • Therefore, the current passing through a circuit if it takes 1 minute for 45C of charge to pass a point is 0.75A.
