In a circuit, an electrician replaces a 4 ft. section of wire with a wire that has a larger diameter. This change in wire diameter will cause which of the following results?
A)The current in the new wire section will be less than in the original wire.
B)The resistance of the new wire section will be less than that of the original wire.
C)A greater power loss in the circuit will occur because of the new wire section.
D)A greater voltage drop across the circuit will occur because of the new wire section.

A larger diameter wire has less resistance compared to a smaller diameter wire, assuming the material and length remain constant. This is because the larger cross-sectional area allows more electrons to flow through with less opposition.
