Extending 15a Circuit to Shed

[electrificator]

I am planning to run power to a very small shed by extending an existing 15a circuit that currently feed only a gate operator (4.5amp). I only need power at the shed for a light and a single receptacle for the occasional small power tool. The gate is fed by (3) #14 wire in PVC conduit about 100'. I plan to tap into the existing junction box at the gate and run THWN #14 wire underground (18" depth) in a 3/4" conduit about 75' to the shed. I will use a small disconnect and a GFCI at the first receptacle. My questions:

1. Will there be a problem with voltage drop if running #14 wire that far? I assume it does no good to run heavier wire unless I replace the existing run of #14 with the same.
2. Is schedule 40 PVC conduit sufficient for running a 120v, 15amp circuit 18" down in a residential yard?
