Why would the voltage drop to 105 in one outlet in your old mobile home?

Check the voltages on the other receptacles in the home. If you find other lower voltages go back and shut that breaker off. Go through out the house shutting off the breakers that have low voltage on them. If other ones are lower see if you can establish if the voltage drop is on the same bus breakers. These will be every alternate breaker. If the breakers that you shut off are every other breaker then the problem is with the incoming utility supply. Give them a call and get them to read the voltage at the meter base. If you can not find any other low voltages in the home then shut the breaker off to that circuit and change the receptacle out for a new one. If the voltage is still low after replacing the receptacle, it could be the breaker that is feeding that circuit.

The wiring in the wall of your house to and from an outlet has a total resistance of typically 0.12 ohms suppose a device plugged into a 120 V outlet draws 10 A of current What is the voltage drop?
Assume the supply as DC (Only resistance given) Voltage drop = 10X10X0.12 = 12V (approx)
There is only 20 volts not 120 volts on outlet that was fine the day before.?
This is strange, check the scale on your meter that you are reading, to make sure that you are on the correct voltage scale. If the reading is correct the suggestion would be to get an electrician to look into why there is such a voltage drop on the outlet. Don't read the voltage across the device, read the voltage from the "hot" wire to ground. That should be 120 volts. If you get that reading then there is a problem with the neutral. It could be loose or have a high resistive condition.
Can you plug a 110V appliance into a 115V outlet?
120 Volts and 115 Volts refer to the same thing in the US. Residential electricity is provided at 120 Volts from the utility. High current devices such as motors are often rated at less than the supplied voltage (such as 115 Volts) because it is expected that there is a small amount of voltage drop in the circuit feeding them. The National Electric Code allows a 5% drop in voltage from the electric service so a 5 Volt drop from 120 Volts is OK.
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.
Why drop voltage in xlpe cable is more than PVC cable?
The voltage drop in a wire has nothing to do with the insulation. Voltage drop has to do with the cross sectional area of the wire.

What would be the voltage drop across two 25 resistors in parallel if the source voltage were equal to 9v?
The voltage would 9V minus any drop in the battery.

What would the results of voltage drop test be if the circuit is open?
voltage drop is zero bcz in open ckt current will be zero
On a standard three prong AC outlet what should the AC voltage measure between neutral and ground?
Zero, or very close to it. If there is a large neutral current flowing, voltage drop on the neutral leg could cause a volt or so to read between the two. If you read full line voltage, the outlet is wired wrong!
What is volts drop?
the voltage drop means whenever the conductor passing through the supply voltage, according to the resistivity property to reduces the some amount of voltage that drop is known as voltage drop for example the resistance is used to drop the voltage to the circuit.............................................

Is there a rule to distance of cable from a power source to low voltage lighting without voltage drop and do you have to put transformers or outlets in the yard?
Voltage drop depends on the size & length of the wire and the wattage of the bulbs. If they make an LED replacement bulb , you would hardly notice the voltage drop.
What is the voltage drop using?
Voltage drop is caused by circuit resistance
When measuring voltage drop across a switch what is the maximum allowable voltage drop?
The voltage drop should be as close to zero as would be readable by a typical volt meter. If it is measurable you likely have a problem with corrosion or oxidation in switch that is increasing resistance. If you can measure a voltage drop across a closed switch contact, replace the switch. Or the switch is open, try flipping the switch!
What would cause high voltage drop readings?
High resistance on the feeder to the load will cause voltage drop at the load end of the circuit. If this is happening, do the calculations for voltage drop, using the amperage of the load, voltage of the load, the size of the wire feeding the load and the distance from the distribution panel to the load.
The voltage drop in line can be decreased by?
The voltage drop in a line can be decreased by
