Answer 1

Parallel combination

Step-by-step explanation:

There are two types of combination of resistances.

1. Series circuit :When the resistances are connected back to back, the combination is called series combination. Here, the current in each resistance is same. The effective resistance is given by

R = R' + R''

2. Parallel combination: When the one ends of all the resistances connected at a point and the other end is connected at other point, the combination is said to be parallel. Here, the voltage difference is same for all the resistances.

The effective resistance is given by

`(1)/(R)=(1)/(R')+(1)/(R'')`

So, to get the effective resistance is small, we have to connect the resistances in parallel combination.
