Question

The equivalent resistance across A and B

Answer 1

Answer:

2 Ω

Explanation:

let us consider potential at point A to be 'V' and at point B to be 0.

potential at other 4 points [above and below resistors be x].

thus 2.4 ohm and 2.4 ohm are in parallel and 4 ohm and 1 ohm are in parallel.

EQUIVALENT RESISTANCE = 2.4x2.4÷2.4+2.4 + 4x1÷4+1

= 1.2 + 0.8 = 2Ω
