Answer 2

I hope you want to find the equivalent resistance,

For simplicity lets name each of the resistors,

• 5ohm = A
• 15ohm =B
• 10ohm =C
• 20ohm =D

now we can see that the C and D resistors are connected in series,

so the total resistance = resistance of C + resistance of D

= 10+20 = 30ohm...(i)

we can see the A and B resistors in series,

so total resistance = 5 + 15 = 20ohm..(ii)

now we can observe the (i) and (ii) resistors in parallel,

@$so \: \frac{1}{total \: resistnce} = \frac{1}{(i)} + \frac{1}{(ii)}$

$= \frac{1}{30} + \frac{1}{20}$

on cross multiplying,

$\frac{20 + 30}{600} \\ = \frac{50}{600} \\ = 0.83ohm(approx.)$

so total resistance = 1/0.83ohm ( any doubt arises please check @ statement)
