Answer:
(a) 10 ohm
Explanation:
When the resistors are connected in parallel then its overall resistance is decreases even it is less than the smallest resistance which are connected in parallel.
For example if n resistors are connected in parallel each of value R then its equivalent resistance will be R/n
So here 1000 resistors are connected in parallel each of 10 k ohm so the equivalent resistance will be [tex]\frac{10000}{1000}=10\ ohm[/tex]
So the option (a) will be correct answer
