Three resistors with magnitudes 2,4 and 8 ohm are connected in parallel. The equivalent resistance of the system would be

Options

  1. Aless than 2 ohm
  2. Bmore than 2 ohm but less than 4 ohm
  3. C4 ohm
  4. D14 ohm

Correct answer

A. less than 2 ohm

Step-by-step solution

aligned & 1 / R =1 / R ₁+1 / R ₂+1 / R ₃ & =1 / 2+1 / 4+1 / 8=7 / 8 aligned R =8 / 7 , It is more than one and less than 2.
