What is the current drawn from the battery of $6 V$ ?

Options:

Answer:

Solution:

$R_{e q} = \frac{2 R_{1} R_{2} + R_{1} R_{3} + R_{2} R_{3}}{R_{1} + R_{2} + 2 R_{3}}$

$= \frac{2 \times 2 \times 4 + 2 \times 2 + 4 \times 2}{2 + 4 + 2 \times 2} = \frac{16 + 4 + 8}{2 + 4 + 4} = \frac{28}{10} = 2.8 Ω$

$i = \frac{6}{2 + 2.8} = \frac{6}{4.8} = 1.25 A m p$
