Question

please answer this guys
no spams please​

Answer 1

the two resistance are in series 6ohm and 6ohm

so req = 6+6 = 12

then parallel

so 1/req = 1/6+1/12

= 2+1/12 = 3/12

req = 4

Answer 2

Answer:

4 ohm

Explanation:

6 +6 is in series= 12

then in parallel

$\frac{1}{12} + \frac{1}{6 } = \frac{1}{rp} \\ \frac{1}{12} + \frac{2}{12} \: \: \: \: lcm = 12 \\ \frac{3}{12 } = \frac{1}{rp } \: \: reseprocal \\ rp = \frac{12}{3} \\ \\ rp = 4ohm$
