Question

A charge of 90 C passes through a wire for 30 seconds. Then the current in the wire will be:

Options
  • A

    З А

  • B

    0.3 A

  • C

    3 mA

  • D

    0.3 mA

Explanation

Explanation is given as an image.

That's correct option. As current passing through circuit is given by

Current= charge/time

= 90/30

=3A

That's not the correct option as per calculation.
