well it is measuring the amount of electricity energy used
the use and consistency of the use
Most calculators use 1.5 volts from small button-cell batteries, such as LR44 or CR2032.
American use both watts and volts to measure units of electricity.
It depends which country you are in. Some countries use 115 Volts AC for household supplies, some use 220, 230 or 240 Volts AC. See the link below for a list of which countries use which voltage.
To convert watts to amps at 120 volts, use the formula: Amps = Watts / Volts. For 1500 watts at 120 volts, the calculation would be: 1500 watts / 120 volts = 12.5 amps.
12 volts.
the use and consistency of the use
An electrical device doesn't really "use" volts. The volts in a minute are the same as the volts in a second or in a day - since the voltage tends to remain fairly stable.
The United States is one country that uses 110 volts. Also, Mexico and Canada are also other countries that use 110 volts.
A car battery has usually 12 volts.
Use a full wave bridge rectifier.
