When the starter motor on a car is engaged, there is a 300 A cunent in the wires between the bauery and the motor. Suppose the wires are made of copper and have a total length of 1.0 m. What minimum diameter can the wires have if the voltage drop along the wires is to be less than 0.50 V? Problems

diameter of transmission is 3.473 mm

Explanation:

given data

current = 300 A

total wire length = 1.0 m

voltage drop = 0.55 V

solution

as here Resistivity of copper is = 1.68 × ohm- m

so we get here resistance of wire that is

resistance =    ..............1

R =  

R = 1.774 ×  ohm

and now we get diameter of wire that is

R =    .............2

d² =     ...............3

put here value

d² =  

d =

d = 3.473 × m

d = 3.473 mm

so diameter of transmission is 3.473 mm
