Two resistances, one 12 S and the other 18 S, are connected in parallel. What is the equivalent resistance of the parallel combination

Respuesta :

MathPhys

Answer:

7.2 Ω

Explanation:

For resistors in parallel, the equivalent resistance is:

1 / R = 1 / R₁ + 1 / R₂

1 / R = 1 / 12 + 1 / 18

R = 7.2
