Question

what we do when resistors in parallel​

Answer 1

• When resistors are parallel, current is the maximum since resistance is the least

• We keep these type of connections in our home since all the resistors are not connected in series, it won't disrupt the current or the circuit if there is a short circuit or something happens to one of the resistors.

Eg: If one of the light bulbs in our house is broken due to a problem with the circuit, it won't shut down the other bulbs or the other part of the circuit since the connections is parallel. Thus this is an advantage for this type of connection.

FORMULA : 1/R(parallel)= 1/R + 1/R

                    ∴ R(parallel) = R/2

( In '1/R', 'R' represents the value of the resistor. So if there are two resistors of 2 Ω , it will be 1/2 + 1/2 = 2/2 = 1)
