Answer 9

What is the difference between arrangement in (a) and arrangement in (d) ?

Answer 10

A is parallel and D is series

Answer 11

Oh never mind! I got the answer. It's D

Answer 12

Thank you everyone

Answer 13

I thought D is Correct ^.^

Answer 14

Wait..
no it really doesn't make much sense

If I have a bulb and connect it across the battery... is the bulb in series with the battery or parallel?
Its both

Cause the bulb gets the same voltage as the battery and since it is only one component it gets the same current as the battery..

Series parallel would only make sense if there are more than just 2 components in a given electrical network!
