Q: An electric current of 0.5 A flows in the filament of an electric bulb for 5 min. What will be the electric charge flowing through that wire?
  • A. 400 C
  • B. 200 C
  • C. 240 C
  • D. 150 C
Correct Answer: Option D - Given that, t = 5 x 60 = 300 seconds I = 0.5 Ampere The amount of charge flowing through the wire Q = I x t Charge (Q) = 300 x 0.5 = 150 coulomb
D. Given that, t = 5 x 60 = 300 seconds I = 0.5 Ampere The amount of charge flowing through the wire Q = I x t Charge (Q) = 300 x 0.5 = 150 coulomb

Explanations:

Given that, t = 5 x 60 = 300 seconds I = 0.5 Ampere The amount of charge flowing through the wire Q = I x t Charge (Q) = 300 x 0.5 = 150 coulomb
