Given 'n' resistors of resistance R Ω. How should they be connected to get the minimum effective resistance?
Parallel
Series
A combination of series and parallel
Can't say
In order to get minimum effective resistance, we need to connect the resistances in parallel.
Given 'n' resistors of resistance R Ω. How should they be connected to get the minimum effective resistance:
How will you connect three resistors of 3 Ohm, 4 Ohm and 7 Ohm respectively so as to obtain a resultant resistance of 3.5 Ohm?
For n resistors of equal resistances in combination, parallel connection gives larger effective resistance than the series connection.
