There are five resistances of 1 ohm each. If the initial three resistance are joined in parallel and rest two are joined in series, then the final resistance is
Text Solution
Verified by ExpertsThe correct answer is:
C
Calculate Parallel Resistance
The equivalent resistance ( 
) of three 
resistors joined in parallel is calculated using the formula:
Substituting 
:
Calculate Total Series Resistance
The remaining two 
resistors are connected in series with the parallel combination ( 
). The total resistance ( 
) is the sum of these resistances:
Substituting the values:
