Answer this question
Study the marking See what earns credit and compare it with a full-mark answer.

Marking points

  1. 1 State that the current decreased.

Full-mark answer

The current decreased.

Why this answer loses marks

The current increased.

This gives the opposite effect of increasing resistance.
