Q77 / 270 · NDA 2021 (Phase 1) · General Ability

A current of 1.0 A is drawn by a filament of an electric bulb for 10 minutes. The amount of electric charge that flows through the circuit is

  • A
    0.1 C
  • B
    10 C
  • Correct answer
    C
    600 C
  • D
    800 C

Solution

we are given current $=1 \mathrm{~A}$ time $=10 \mathrm{~min}=10 \times 60 \mathrm{sec}=600 \mathrm{sec}$ using the formula $\mathrm{I}=\frac{\mathrm{Q}}{t}$, where I is the current in Amperes and $1 \mathrm{~A}=\frac{\mathrm{Q}}{600 \mathrm{sec} .} \Rightarrow \mathrm{Q}=1 \times 600=600^{\circ} \mathrm{C}$

Hence, the correct answer is option: 'C'.
