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

Rahul went to an electronics shop to get his father's old radio set repaired. The radio mechanic required resistances of 1.5 Omega and 10 Omega to repair the radio set properly but he had only a large number of 3 Omega resistors. The radio mechanic made many attempts but could not get the right combinations of 3 Omega resistors to obtain 1.5 Omega and 10 Omega resistances. Rahul had studied combination of resistors in class X. Rahul thought for a while and then joined some 3 Omega resistors in two different ways to obtain the required resistances. (a) How did Rahul obtain 1.5 Omega resistance by joining a number of 3 Omega resistors ? (b) How many 3 Omega resistors were combined together to obtain 1.5 Omega resistance ? (c) How did Rahul obtain 10 Omega resistance by joining a number of 3 Omega resistors ? (d) How many 3 Omega resistors were combined together by Rahul to obtain 10 Omega resistance ? (e) What values are shown by Rahul in this apisode ?
