Question

Find the equivalent resistance between A and B of the given circuit.

विकल्प

• 62.5 Ω

• 48.62 Ω

• 32.5 Ω

• 30 Ω

Answer 1

48.62 Ω

Explanation:

The 4 Ω, 5 Ω and 6 Ω resistors are in parallel:

`1/R = 1/4 + 1/5 + 1/6`

`1/R = 37/60`

R = `60/37`

R = 1.62 Ω

This is in series with 14 Ω, 8 Ω and 25 Ω:

R_eq = 1.62 + 14 + 8 + 25

= 48.62 Ω
