Question
In parallel combination, the total resistance of the circuit becomes ___the individual resistances.
Answer: Option D
:
D
When resistors are connected in parallel,the equivalent resistance is less than the lowest resistance in the circuit.
Proof is as follows:
As we knowwhen R1,R2,R3...Rn resistors are connected inparallel circuit, the equivalent resistance of the circuit is
1Req=1R1+1R2...1Rn
1Req≥1Ri∀i∈{1,2,3,....,n}
⟹Req≤Ri
