1

what is resistance measured in?

ohms

2

when does the resistance in a wire increase

the thickness of the wires decreases
as the length of the wires increases

3

whats the equation for calculating resistance?

potential difference = current x resistance

4

what is a series circuit?

components connected one after the other on the same loop

5

if one lamp breaks in a series circuit, what will happen to the other one?

it wont light

6

what is a parallel circuit?

components connected on separate loops

7

if a lamp breaks in a parallel circuit, what will happen to the other one?

it will still light
