Parallel Circuits

Q1:

Six resistors are in parallel. The two lowest-value resistors are both 1.2 k. The total resistance

A is less than 6 k

B is greater than 1.2 k

C is less than 1.2 k

D is less than 600 

ANS:D - is less than 600 

Let, assume 1.2 low, and 0ther 4 resistor value 2400.

1/1200 + 1/1200 + 1/2400 + 1/2400 + 1/2400 + 1/2400,
= 2400/8 = 300 ohm,
Option D.
