A1.5m wire carries a 5 a current when a potential difference of 68 v is applied. what is the resistance of the wire?

Resistance = (voltage) / (current)

Resistance = (68 V) / (5 A)

Resistance = 13.6 ohms

Since we already know the voltage and the current, we don't need to know the length of the wire.  It makes no difference.

i had this question and the answer was 3.15 miles.

a) 0 miles  

b) 0.4 miles
