Question

How can three resistors of resistances 2 ohm, 3 ohm and 6 ohm be connected to give a total resistance of 4 ohm? Draw an appropriate circuit diagram
please answer if u know​

Answer 1

Answer:

Connect 6 ohm resistor and 3 ohm resistor in parallel combination and connect 2 ohm in series combination.

Step-by-step explanation:

We know that

1/Rp=1/R1+1/R2 (Rp means resistor in parallel)

1/Rp=1/3+1/6

1/Rp=6+3/6

1/Rp=9/18 =1/2

Rp=2 ohm

Now;

Rs= Rp+2 (Rs means resistor in series)

Rs=2+2=4 ohm.

Now; Rf =4 ohm (Rf means final resistance)
