Respuesta :

All the three resistors are in parallel because the current is getting divided in each branch.
Therefore the equivalent resistance is 
1/R = 1/3 + 1/6 + 1/9 = 11/18
Therefore, R = 18/11 = 1.6 ohms 

The  equivalent resistance of the circuit is mathematically given as

R= 1.6 ohm

Option B is correct

What is the equivalent resistance of the circuit?

Generally, the equation for the Resistance   is mathematically given as

1/R = 1/R1+1/R2,,,

1/R=1/3 + 1/6 + 1/9

1/R= 11/18

Hence

R = 18/11

R= 1.6 ohm

In conclusion, the equivalent resistance

R= 1.6 ohm
