For typical house wiring you would use 14 AWG wire for 15 amps. The resistance of 125 ft of 15 AWG copper is about .316 ohms. For a full load of 15 amps your voltage drop would be 4.74 volts. If you up the size to 12 AWG the resistance is .198 ohms and the voltage drop is 2.97 volts. So for your application use 12 AWG with a 15 amp breaker.

∙ 8y agoTo answer this question it has to be stated whether the 3.2 is a percentage of the circuits voltage or 3.2 volts of the circuits voltage. Or just state what the circuit voltage is.

What wire size will carry 50 amps 200 ft 220 voltage?
Actual voltage would be 240V. 4 AWG copper is capable of carrying 50A. At 200 ft, with a 50A load, voltage drop would be about 6V, which is within the acceptable 3% voltage drop for a branch circuit.
What is the minnimum size equipment grounding conductor required by the NEC for a branch-circuit protected by a 50-ampere rated circuit breaker?
#10 copper
What is the minium branch -circuit wire size that may be installed in a dwelling?
Under modern code, the 14 AWG copper conductor is the smallest branch-circuit wiring size, based upon 15A overcurrent protection.
What is the maximum length allowed on a 20 amp rated branch circuit if is a120 volt single phase?
A maximum distance of 52 feet will limit the voltage drop to 3% or less with a #12 copper conductor delivering 20 amps on a 120 volt system.
Open circuit and short circuit test?
Open circuit means the circuit is not continuous . A short circuit is continuous but has a fault connecting between either live to neutral or earth .As result of this we saw that this answer is unsufficent to explain short and open circuit on the other hand you can use this answer also like i did:)
Why does zinc and copper create a higher voltage than copper and copper in a circuit?
It is very weird and I am gonna help. Zinc and copper create a higher voltage than copper and copper because zinc has a higher voltage than copper so copper plus zinc equals more than copper plus copper.
Is gold used in circuit breakers?
Certainly not in the case of high-voltage circuit breakers. Probably not in low-voltage circuit breakers, as copper is a better conductor and has a higher melting point.

What are motherboard traces?
copper circuit paths called traces. it carries signals and voltage across the motherboard.
How does voltage works?
voltage means the amount of electrical energy there is.In electrical engineering and physics there are expressed by (V).so I can say that there are 200V in these circuit. Or 200 voltage of electricity run thought the circuit or copper board as most people call them.
Why do you put the meters in the high voltage side in the short circuit test?
in the short circuit test we applied supply voltage on L.V side and short circuit the H.V side and connect the ammeter in H.V circuit to measure the short circuit current. with the help of s.c test we measure the copper losses in the transformers.

What size electrical wire underground 230 volt 60 amp 800 feet?
NEC recommends maximum allowable voltage drops not to exceed 3% on a branch circuit. For feeder/ branch combos the NEC recommends that the voltage shall not drop by more than 5% to the furthest outlet. The main consideration that is enforced is NEC 250-122. You must compensate your grounding conductor when you increase in conductor size to compensate for voltage drops. Direct bury or conduit: #4/0 copper provides for 2.95% #2/0 copper provides for 4.35% #1/0 copper provides for 5.19% Interestingly enough, using a separate calculator 3/0 copper with 3% voltage drop can be 780.5 feet long.

Under modern code, the 14 AWG copper conductor is the smallest branch-circuit wiring size, based upon 15A overcurrent protection.
What is the purpose of open circuit test and short circuit test of a transformer?
An open-circuit test is done with the transformer running at its rated voltage but with no load. This measures the power lost in the magnetic core. (IR Losses) A short-circuit test is done with the transformer running at its full rated current in all windings but at a low voltage. The secondary is shorted and the primary voltage is adjusted to give the rated current. This measures the power lost in the copper windings. (Copper losses)
