Question

module 3 test
ex. 4 - 5
a 120 volt line is protected with a 15 amp fuse. will the fuse carry a 6 ω load?
yes - because the current is below the rating on the fuse (0.002a)
no - because the current is to high for the fuse (200a)
yes - because the current is below the rating on the fuse (2a)
no - because the current too high for the fuse (20a)

Explanation:

Step1: Aplicar la Ley de Ohm

La Ley de Ohm establece que \(I=\frac{V}{R}\), donde \(V = 120\) V y \(R=6\) \(\Omega\).

Step2: Calcular la corriente

Sustituir los valores en la fórmula: \(I=\frac{120}{6}=20\) A.

Step3: Comparar con la fusible

La fusible es de 15 A. Como \(20>15\), la corriente es demasiado alta.

Answer:

No - Because the current too high for the fuse (20A)
