What is used as an abbreviation for electrical current?
Electrical current is measured in Amperes which is abbreviated to amps. When dealing with formulae the letter I is used to represent current, for example: Power = Voltage × Current = volts × amps = V × I Small currents in electrical engineering use the lower case i; this can cause confusion with the lower case i that mathematicians use for √-1, so they use j for √-1 instead.

Asked in Science, Energy, The Difference Between
What is the difference between objects that use electricity from power stations and those that use electricity from batteries?
Technically, you are speaking about the delivery of current. Electricity is one type of current. The current has two differences: The current from batteries has a much lower voltage, and it is DC, while the electricity from the electrical plug is AC. Devices that use current have to be adapted to these two situations. Some devices are only battery powered, e.g. flashlight. Other devices have internal mechanisms to switch the power current between battery and electrical outlet, e.g. a laptop.
