What is the relationship between current & resistance?

• When resistance increases current decreases

• When resistance increases current increases

• When resistance decreases current decreases

• There is no relationship between Current and Resistance

What is the difference between series and parallel circuits?

• Parallel circuits have multiple paths and series circuits have one path

• Parallel circuits have one path and series circuits have multiple paths.

• Parallel circuits and series circuits are the same.

• Parallel circuits have a magnetic field and series circuits do not.
