Question

1. Connecting two AA batteries in parallel will give an effective battery that has:

a) The same emf with a larger internal resistance

b) The same emf with a smaller internal resistance

c) A larger emf with a smaller internal resistance

d) A larger emf with a larger internal resistance

2. Connecting two AA batteries in series will give an effective battery that has:

a) A larger emf with a smaller internal resistance

b) A larger emf with a larger internal resistance

c) The same emf with a larger internal resistance

d) The same emf with a smaller internal resistance

Explanation / Answer

1) in parallel ,

same emf exists

and Net resistance is smaller that any other least individual value

So correct option is B)

2) in series,

larger emf exists and net resisatnce is larger than any other individual greatest value
so the correct option is b)
