If we require the maximum resistance from a number of given resistors, we connect *
1 point
all in series
all in parallel
less resistors in series and more in parallel
more resistors in series and less in parallel
Answers
Answer:
- All in series is the correct answer
Explanation:
To get maximum resistance from a number of given resistors , we connect all resistors in series . Because we know that in series we calculate the equivalent resistance by the sum of resistance of each resistors.while in parallel combination we calculate equivalent resistance by the sum of reciprocal of its individual Resistors .
Formula for calculating the Equivalent Resistance in series.
- Req = R1 + R2 + Rn
where,
Req is the equivalent or total resistance
R1 , R2 & Rn are the Resistance of Resistors.
Required Answer :-
All in series
Because if we connect all resistor in parallel then it will be less than series
Let's see how
Take 2 resistor of 1 and 2 ohm
In parallel
1/Rn = 1/1 + 1/2
1/Rn = 2 + 1/3
1/Rn = 3/3
1/Rn = 1 Ω
In series
Rn = R1 + R2
Rn = 2 + 1
Rn = 3 Ω
Therefore, Option A is correct
