Question

five resistance of 25 ohm each are connected in parallel five such combination are connected in series what is the total resistance​

Answer 1

Answer:

The total resistor value is 7 ohms, and in series resistances, the values are summed together. So when one of the series resistors is 5 ohms, the other is 2 ohms.

The second resistance is expressed as a series of parallel resistances. The equivalent value of the parallel dose equals the sum of the inverse of each resistor:

1/R=1/R1+1/R2+ … + 1/Rn

We know R must be 2 ohm and R1, R2, .. Rn are 6 ohm, so:

1/2=n/6 => n = 3
