Question

CALCULATE THE EQUIVALENT RESISTANCE BETWEEN P and Q
1. 6 ohm
2. 3 ohm
3. 7 ohm
4. 4 ohm​

Answer 1

This is a Wheatstone Bridge coz 

R1/R2 = R3/R4

So, The diagonally connected wire can be neglected

Hence R1 and R2 are in series 

Req = 2 + 3 = 5 ohm

Similarily, R3 and R4 are in series 

Req = 4 + 6 = 10 ohm

THESE TWO Req ARE IN PARALLEL COMBINATION

1/Req = 1/10 + 1/5

1/Req = 3/10

Req = 10/3

Req = 3.33 ohm
