Two cylindrical rods, one copper and the other iron, are identical in lengths and cross-sectional areas. they are joined, end to end, to form one long rod. a 12-v battery is connected across the free ends of the copper-iron rod. what is the voltage between the ends of the copper rod?

Vc = 2.41 v

Explanation:

voltage (v) = 16 v

find the voltage between the ends of the copper rods .

applying the voltage divider theorem

Vc = V x ()

where

Vc =  V x ()

Vc = V x ()

Vc = V x ()

where

Vc = 16 x ()

Vc = 2.41 v

what are the options.

explanation:

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
