Question

three resistors each of 3 ohm are connected in parallel.calculate tjeir equivalent resistance. ​

Answer 1

Answer:

equivalent resistance is 1 ohm

Explanation:

Answer 2

Answer:

Equivalent resistance = 1 ohm

Explanation:

In Parallel combination ,

we calculate the equivalent resistance as

1/R = 1/R1+1/R2+1/R3 ;  

where r1 ,r2 ,r3 = 3 (given in the question )

so now putting values in the above formula

1/R = 1/3 +1/3 +1/3

     =( 1+1+1) / 3

      = 3/3

       = 1 ohm  

(ohm is the unit of resistance )

so, R=1 ohm
