Question

*To get 2 Ω resistance using only 4 Ω resistors, the number of resistors required is ?*
what is answer please tell me​

Answer 1

Answer:

Explanation:

Total number of resistors used in the circuit is 3 in order to get 2 ohms equivalent resistance.

Explanation:

In this case, to get 2 ohm resistance using only 6 ohm resistor, we need to find the number of resistors.

When 3 resistors of 6 ohms are connected in parallel, then the equivalent resistance is given by :

1/R=1/R1+ 1/R2+1/R3

1/R= 1/6 + 1/6 + 1/6

R = 2 ohms

Answer 2

SOLUTION

TO DETERMINE

The number of resistors required to get 2 Ω resistance using only 4 Ω resistors

EVALUATION

We have to get 2 Ω resistance using only 4 Ω resistors

Since the resultant is lesser than the individual

So the resistors are to be connected in parallel

Each of the are of equal resistance of 4 Ω

Let the required number of resistors = n

So by the given condition

$\displaystyle \sf{ \frac{1}{4} + \frac{1}{4} + ...(n \: times) = \frac{1}{2} }$

$\displaystyle \sf{ \implies \frac{n}{4} = \frac{1}{2} }$

$\displaystyle \sf{ \implies n = \frac{4}{2} }$

$\displaystyle \sf{ \implies n = 2}$

FINAL ANSWER

The number of resistors required = 2
