Question

A piece of wire of resistance 16 kΩ is cut into four equal parts and all the pieces are connected in
parallel to each other. The new combination (parallel) of resistor is equal to 10n ohm. What is the
value of n?

Answer 1

We know that the total resistance is 16000ohm.
Hence by dividing it rinto 4 equal will also divides it's resistance in the same ratio.
That is each resistor will be of 4000ohm.
Hence the eq. becomes as follows.....

10n=4000
=>. N=400ohm Ans.!!
