Question

1.will current flow more easily through a thick wire or a thin wire of same material,when connected to the same source ? why?
2. A wire of a given material having length l and area of cross section A has a resistance of 4 ohm.what would be the resistance of another wire of that same material having length l/ 2 and area of cross section 2A

Answer 1

Hi
This is your answer

1. Current will flow more easily through thick wire because thik wire have less resistance as compared to thin wire which has very high resistance and due to less resistance in thick wire current will flow more easily.

2.See the image for second explanation and ask of there is any problem.
