A 1.5m wire carries a 6 A current when a potential difference of 68 V is applied. What is the resistance of the wire?

Respuesta :

Answer:

[tex]11.3 \Omega[/tex]

Explanation:

We can find the resistance of the wire by using Ohm's law:

[tex]V=RI[/tex]

where

V is the voltage applied

R is the resistance

I is the current

In this problem, we know I = 6 A and V = 68 V, so we can re-arrange the equation to find the resistance of the wire:

[tex]R=\frac{V}{I}=\frac{68 V}{6 A}=11.3 \Omega[/tex]
