The quantity of a charge that will be transferred by a current flow of ( 20 ) A over ( 1 ) hour ( 30 ) minutes period is

Options

  1. A( 10.8 10³ C )
  2. B( 10.8 10⁴ C )
  3. C( 5.4 10³ C )
  4. D( 1.8 10⁴ C )

Correct answer

B. ( 10.8 10⁴ C )

Step-by-step solution

Given, I=20 ~A ; t =1 hour 30 minutes =90 minutes =90 60 seconds Therefore, charge transferred Q=I t=20 90 60=108 10³ C Thus, Q=10.8 10⁴ C
