Angry Can you connect 14-2 wire to 12-2

I just recently installed a 50' NMWU 12-2 wire underground ,from my work shed, to an existing outside outlet in the yard. This outlet runs back 110' to the house. I did not check the size of wire prior to this installation and unfortunatley the wire is only NMU 10 14-2 back to the house. Can i still connect these two for power.Will there be a load loss , too much resistance or any other hazards for it to work properly. I do realize it can only be a 15amp circuit. thanks

Yes, you can connect the #12 to #14. In this application, the #12 will work better than the #14, so your "mistake" is fortunate.

How much voltage drop you have will depend on what you plug in at the existing outlet and/or at the shed. But 160 feet is a long way to run 120-volt power, so I wouldn't use too much. A small hand drill would probably be okay if there was nothing else powered by the circuit (i.e., work in the daylight).
