The neutral will have the same current as the live conductor. It is neutral (connected to ground) for safety

Part 1//
In a single phase 2-wire system, neutral line-wire always carries the return current which is equal to the phase current under normal condition.
Part 2//
In an electric system, current will flow when you make a closed circuit. For example - supply source (generation), phase-supply-wire, user equipment, return neutral-wire and back to the supply source make a closed circuit. Any break (open point like an OPEN switch) in-between will stop the current flow and the system will not work.
The neutral wire will help make a complete closed circuit.

In electrical circuits there is a supply line and a return path, for your car it is usually a +12 volts DC suply line. The chassis is ground and the return path.
In homes it is usually 120 volts AC alternating "single phase" current, and power is supplied on the "hot " line. The "neutral" line is the normal return line. They are tied together at the junction box.
The ground is the safety leg and usually does not carry any current of significance unless something is wrong.

The neutral is the return path back to the source. And , yes, the neutral carries current. Here's some great info on electrical theory and principals.
