Consider the following part of an electric circuit: The total electrical resistance in the given part of the electric circuit is

Options

  1. A15 8 ohm
  2. B15 7 ohm
  3. C15 ohm
  4. D17 3 ohm

Correct answer

B. 15 7 ohm

Step-by-step solution

The net resistance of the given circuit is calculated by series combination of (1 / 2++1 / 4+1 / 8) ohm and 1 ohm= (8 /7+1 ) ohm =15 / 7 ohm
