To calculate the change in temperature, subtract the initial temperature from the final temperature. Example: 84.2 degree Fahrenheit - 41 degrees Fahrenheit = 43.2 degrees Fahrenheit. The temperature from morning to afternoon changed by 43.2 degrees Fahrenheit.
It needs 12 volts so it will be the standard modern power supply provides 12 volts of power.
In essence, household voltage is the average amount of electrical energy supplied to an outlet. In the U.S., there are two standard voltages, one for everyday electrical devices and one for heavy-duty appliances.

The same is true for a 240-volt outlet, which was previously designated as a 220-volt outlet.
