Multiple choice

Charge 8/10 passes a point in 4 s. Then current in amperes is __________.

  1. 11 A

  2. 40 A

  3. 0.2 A

  4. 5 A

  5. 320 A

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Current (ampere, A) = charge (coulomb, C) / time (second, s) i = Q / t i = (8/10)/4 i = 2/10 i = 0.2 A.
