Question

1.
Equivalent resistance between two points A and B in the circuit shown will be :
​

Answer 1

Answer:

C) 3 ohms

Explanation:

Refer the attachement for simplified circuit,

Since 3 2 ohms resistors are connected in series, equivalent resistance in this arm is 2+2+2=6

Similarly 3+3=6 is resistance in the other arm

Since two 6 ohms resistors are connected in parallel, the equivalent resistance R' is given by

=> 1/R'=1/6+1/6

=> R'=6/2

=> R'=3 ohms
