What is the resistance value of four 8-ohm horns connected in parallel?

To determine the resistance value of four 8-ohm horns connected in parallel, it's important to understand how resistance works in parallel circuits. In a parallel configuration, the total or equivalent resistance can be calculated using the formula:

1/R_total = 1/R1 + 1/R2 + 1/R3 + 1/R4

For four horns each with a resistance of 8 ohms:

1/R_total = 1/8 + 1/8 + 1/8 + 1/8

This simplifies to:

1/R_total = 4/8

When you simplify 4/8, that gives you 1/2. To find R_total, you take the reciprocal:

R_total = 1 / (1/2) = 2 ohms.

This calculation shows that connecting the four 8-ohm horns in parallel results in a total resistance of 2 ohms. Therefore, this makes the computed resistance value accurate and confirms the correct answer.
