If the device you are powering requires 7 amps of power, then no. You will need to find a replacement cord with 7 amps. Check the power input requirements of the device to find out.
Sure
Yes. The cord only transmits the power. Whatever that goes in is what comes out.
Yes, no problem at all going to a larger ampacity of wire. Larger size wire yes, smaller size wire no.
You need to define what you mean by 2.0 and 1.6.
Yes the rated voltage is a maximum. A 250 v cord might be slightly thicker than one for 125 v. <<>> The voltage rating of an electrical extension cord is the insulation factor of the cord. These cords come in two insulation ratings, 300 volts and 600 volts. If the voltage rating is within the parameters of the cord maximums then it is safe to use it on that voltage. The amperage of the cord is based on the wire size of the cord's conductor. The rating of 10 amps will fall within the #14 cord size. Remember the longer the cord the larger the wire size should be to prevent voltage drop at the connected load end.
No. At 125 volts, the same 15 amp current results in 10 times as much power. Ohm's Law states that amps x volts = power.
You tell yourself the 125 volt receptacle is a 120 volt receptacle. They're the same thing.
Yes.
According to this , yes it will work http/forums.lenovo.com/t5/IdeaPad-S-series-Netbooks/Voltage-Supply-Range-of-the-Power-Adaptor-and-the-cable/td-p/181204 <<>>> The above answer was taken from forums, not the most reliable source of information. No, a 125 volt adapter can not be used in a 220 volt outlet.
NO! There are 50 bulbs in a 2.5 volt string or 125 volts. There are 35 bulbs in a 3.5 volt string or 122.5 volts. If you put 50 3.5 volt bulbs in you will have 175 volts and most american house have 110 volt service so you will have dim bulbs.
Yes, a 110 volt device can be plugged into a 125 volt receptacle. The voltage rating on the receptacle is only there as the highest voltage supply that the manufacturer recommends their equipment be connected to.
A 15 amp 125 volt outlet is a household outlet.
