You are not charged on the value of voltage nor on the value of amperage but the product of the two. Amps x volts = watts. It is this product of the two values that the watt meter measures. That total, times the amount of hours that the watts are used, times the price per kWh in your area, determines the price that you are charged for the power used.
Cost is based on watts not voltage...pkazsr
12 volts is less of power than 18 volts drill
8 gauge will be sufficient with less than a half volt drop
one thousand milli volt= one volt
You can't compare volts and amps in this context. If you mean 18 Volts vs. 14 Volts then the 18 Volt tool will provide more power for the job.
True, 220 volt appliances consume less energy than 110 volt ones, but in order to use them in the US, you would need to convert them to 110 voltage. This is a less efficient use of energy. Plus, 220 volt appliances are a more risky because people can get seriously injured if they get shocked from them.

a little less than one volt will be produced with each potato
No. It requires more that 8.4 volts to charge a 8.4 volt battery. If the 8.4 volt battery is discharged to less than 7.2 volts then it might charge up to 7.2 volts but no higher. Once the voltages are the same then current stops flowing and charging stops.
no.
Check the voltage at the battery with a DC volt meter. It is reads 12.6 volts is it 100% charged. 12.4 volts 75%, 12.2 volts 50%, and 12.0 volts 25% charged. Less than 12.0 volts is a dead battery. If the battery will not hold a charge with the negative cable disconnected it has a dead cell and must be replaced.
Some small electric motors will operate with an input voltage of 10 volts or less. Some bulbs for vehicles will operate on < 10 volts (but less bright than they would operate at their normal 12 volt input voltage.
It reads what the voltage is so maybe the voltage source is 75 volts. Without stating what the voltage is suppose to be it is hard to give an answer to this question.
A volt is a volt is a volt.
A volt is a volt is a volt.
No, 12 volts means 12 volts. Anything less will not work and anything more will not work.
Your alternator has either stopped working or is putting out less than 14 volts, therefore not enough charge is getting to your battery.
