Question

. We have 3 resistors containing 3 ohms each. To yet a resistance of 2 ohms, we should
connect them:
a) in series
b) in parallel
c) two in parallel and third in series with combination.
d) two in series and third in parallel with combination​

Answer 1

Answer:

the answer is d option

Explanation:

one ohm is one v by one a

Answer 2

Option d) is correct .

Given :

Three resistors of 3 ohms resistance.

We have to connect all these resistor such that their equivalent will be 2 ohms.

At first, we will connect two 3 ohms resistors in series .

Then , their equivalent resistance is , 3 + 3 = 6 ohms.

Now, we will connect the last one resistor in series with the above combination.

Therefore , $\dfrac{1}{R}=\dfrac{1}{3}+\dfrac{1}{6}\\\\\dfrac{1}{R}=\dfrac{1}{2}\\\\R=2\ ohms$

Therefore, option d) is correct .

Hence , this is the required solution.
