Practically, how does a parallel connection of resistors help in reducing the effective resistance and increase the current flowing through it?

Expert Answer:

When the resistors are in parallel, the effective resistance is given by:
 
1/R = 1/R1 + 1/R2 , say if the R1 and R2 are the resistors.
 
We know that I, current is inversely proportional to resistance.
 
So, if R is very small, the current would be highest.
 
If the R is high, this would not allow current to flow through it.
