Question

You are provided with 4 resistors of 3 ohm, 3 ohm ,3 ohm and 12 ohm. How will you connect them

so to obtain an effective resistance of :- i) 13 ohm ii) 3.9 ohms. Draw diagrams of the

arrangement​

Answer 1

Answer:

follow me....

Explanation:

The 2 ohm and 3 ohm resistors will be connected in series. This will give a resultant resistance of 5 ohm. Then this arrangement will be connected with the 5 ohm resistor in parallel. This will give a effective resistance of 2.5 ohm.
