Q: An electric current of 0.5 A flows in the filament of an electric bulb for 8 min. What will be the amount of charge flows by electric current?
  • A. 240 C
  • B. 50 C
  • C. 200 C
  • D. 400 C
Correct Answer: Option A - Given, I = 0.5 A t = 8 min = 8 x 60 = 480 sec. Q = ? Electric Current (I) = Charge(Q)/Time(t) 0.5 = Q/(60 × 8) ∴Charge (Q) = 0.5 × 8 × 60 = 240 C
A. Given, I = 0.5 A t = 8 min = 8 x 60 = 480 sec. Q = ? Electric Current (I) = Charge(Q)/Time(t) 0.5 = Q/(60 × 8) ∴Charge (Q) = 0.5 × 8 × 60 = 240 C

Explanations:

Given, I = 0.5 A t = 8 min = 8 x 60 = 480 sec. Q = ? Electric Current (I) = Charge(Q)/Time(t) 0.5 = Q/(60 × 8) ∴Charge (Q) = 0.5 × 8 × 60 = 240 C
