Correct Answer - Option 3 : 600 C

CONCEPT:

Electric current:

• The flow of electric charges through a conductor constitutes an electric current.
• Quantitatively, electric current in a conductor across an area held perpendicular to the direction of flow of charge is defined as the amount of charge flowing across that area per unit time i.e.,

${\rm{Electric\;curernt\;}}\left( {\rm{I}} \right) = \frac{{{\rm{Electric\;charge}}\;\left( {\rm{Q}} \right)}}{{{\rm{Time\;}}\left( {\rm{t}} \right)}}$

• SI unit of current is ampere and it is denoted by the letter A.

CALCULATION:

Given - Electric current (I) = 1 A and time (t) = 10 minutes = 600 sec

• The amount of electric charge that flows through the circuit is\

⇒ Q = I × t

⇒ Q = 1 × 600 = 600 C
