3. Bottom contact
4. Separator

Question 24

Series circuit:

Answer 24

1. Current is the same everywhere
2. Voltage is different, depends on the resistance
3. Resistance is simply added up
4. Current goes through small resistance first

Question 25

Parallel circuit:

Answer 25

1. Current is different
2. Voltage is the same
3. Resistance is 1/r1+1r2
4. Current goes everywhere evenly
