A metal wire has a cross-sectional area that gradually becomes smaller from one end of the wire to the other. How do drift velocity, current density, and electric field vary along the wire?

Suppose that a current-carrying ohmic metal wire has a cross-sectional area that gradually becomes smaller from one end of the wire to the other. How do drift velocity, current density, and electric field vary along the wire? Please explain with the help of equations to support explanation.

Series and parallel

1. Three resistors have values 5 ohms, 2 ohms, and 1 ohms. The first one is followed by the last two wired in parallel. When this arragnement is connected to a battery, which resitor(s) has a) the largest current, b) the largest voltage, and c) the largest power output?

Kirchhoff's rule

Use second Kirchoof's rule to explain why 60-W lightbulb produces more light than one rated 100 W when they are connected in series to a 120-V source. I know that the ratings on lightbulbs are meaningful only at 120 V but that is about it. Please Use Equations to explain this problem.
