You Are Supplied with a Number of 100 ω Resistors. How Could You Combine Some of These Resistors to Make a 250 ω Resistor? - Science

You are supplied with a number of 100 Ω resistors. How could you combine some of these resistors to make a 250 Ω resistor?

Solution

When two 100 Ω resistors are connected in parallel, the value of the combined resistance becomes 50 Ω.
Now to get a resistance of 250 Ω, we must connect two more 100 Ω resistors in series with the above combination.
Therefore, the configuration will be two 100 Ω resistors in series with a parallel combination of another two 100 Ω resistors.

  Is there an error in this question or solution?
