Show how you would connect two 4 ohm resistors to produce acombined resistance of (a) 2 ohms (b) 8 ohms.

You are given resistors of 2 ohms, 4 ohms, and 6 ohms. With the help of these resistors, how can you get a resultant resistance of (i) 12 ohms, and (ii) 3 ohms? Draw diagrams to illustrate your answer.

A student has been given 3 resistances of 3 ohms each. (a) How should he connect these resistances so as to obtain a resultant resistance of 1 ohm ? (b) Draw a labelled diagram to show the combination of these resistances.

How should the two resistances of 2 ohms each be connected so as to produce an equivalent resistance of 1 ohm?

A resistor of 8 ohms is connected in parallel with another resistor X. The resultant resistance of the combination is 4.8 ohms. What is the value of the resistor X?

A current of 2A flows through a 2 ohm resistor when connected across a battery , the same battery supplies a current of 0.5A when connected across a 9 ohm resistor . the internal resistance of the battery is

Your friend needs 10 ohms resistance. He came to you and asked, but you have 40 ohms resistance. Show that their effective resistance is 10 ohms.
