== == Normal is consider from 110 - 120 volts. But occasionally, for a short time...The voltage falls below normal: a sag. Sags are unlikely to damage most appliances, but they can make a computer crash, confuse some digital clocks and cause VCRs to forget their settings. The reverse of a sag is called a swell or surge: a short duration increase in the line voltage. This disturbance might upset sensitive appliances, and damage them if it is a very large or very long swell. For this reason you need to install a Surge Protector on all sensitive electronics. Computers, Printers, Scanners, Fax, TVs, VCR, DVD, etc. If you are continually running a line voltage of over 120 volts, as measured with a good accurate meter, I suggest you call your electric company immediately. This is not normal, and there may be a problem with the transformer outside your home. <><><>
125 to 130 Volts is the present standard utility voltage
Normal was 110 Volts when I was a kid in the 50s.
I haven't seen anything under 125 volts in years.
The voltages have been raised to accommodate increased loading. <><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

It is not typical for a 120V to 24V system to reduce to 28V. The voltage should decrease from 120V to 24V. If you are measuring 28V, there may be an issue with the measurement or the equipment itself. It's important to double-check the connections and equipment to ensure they are functioning properly and as expected.
To measure house current voltage, a digital voltmeter (DVM) is typically set to the 200V AC range. This range is suitable for measuring standard household voltages, which in the U.S. typically fluctuate between 110V and 120V. Using this range ensures accuracy and prevents damage to the meter, as it can comfortably handle the expected voltage without exceeding its limits.
No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V side to the neon sign and you should have light. Transformer should be at least 100va. This will give you an output of .83 amps at 120V
To calculate the number of amps, you need to know the voltage of the circuit. Using the formula Amps = Watts / Volts, if the voltage is 120V, then 9.8kW at 120V would be approximately 81.67 amps.
To calculate the amperage for 2kW, you need to know the voltage of the circuit. For example, if the voltage is 120V, then the amperage would be 16.67A (2000W / 120V = 16.67A). If the voltage is 240V, then the amperage would be 8.33A (2000W / 240V = 8.33A).

100 Volts
There should be no voltage on the neutral wire to ground. This is a serious situation. Call a qualified electrician to check this out.
It is 120V/60Hz

It is the 'as if' voltage in an AC circuit. Referred to as Vrms 120 volts in your house is Vrms, the effective voltage, 'as if' it were DC 120V, can do the same work. But 120VACrms is a sine wave with a peak voltage much higher than 120 volts.
120V appliance will not work on 220V. Use an instrument transformer or voltage regulator to adjust the high voltage to the desired level.
Yes ,it's the same voltage.You have a +-5% of voltage range
there is 120V across the circuit.
In America, a 2-pole breaker is controlling 240V. 120V per leg.
The transformer steps down the voltage from 600kilo volts which is what is at the power pole/lines to multiple strands of 120v or hot wires which is what your house runs off of.
there is 120V across the circuit.
