#### Question

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?
