When two conductors with the same length and different cross-sectional area are connected in series, they compare the current and voltage. The thin one is ab, and the thick one is BC
The series current is equal
U=IR
Thin resistance, high voltage at both ends
Uab>Ubc
How do the factors affecting voltage and current, material, length, cross-sectional area and temperature affect it?
The relationship between voltage and current, in line with Ohm's law, that is, current = voltage / resistance. Many factors affect the resistance, 1) material determines the conductivity, in terms of conductivity, silver is better than copper, copper is better than iron
