Loop Rule

Question 1

What is the loop rule in relation to current?

Answer 1

When current moves in the same direction as the loop the potential difference on a particular resistor is negative and vice versa.

Question 2

What is the loop rule in relation to battery terminals?

Answer 2

When the loop moves from positive terminal to negative terminal the EMF at that point is negative and vice versa.

Current normally moves from negative terminal through to positive terminal.
