Why is i used for electrical current?
It is mostly convention. However this produces conflicts with the conventional mathematics usage of i as the square root of -1 in complex numbers, so in electronics the convention is to use j as the square root of -1 instead when working with complex numbers in the analysis of AC circuits.

An ammeter is used to measure an electric current. Alternatively, you can use a multimeter , set to an appropriate current range.
An ammeter, either shunt or inductive. A shunt is an inline resistor of a small, known resistance. Knowing the resistance and the voltage one can calculate the amperage by Ohm…s law, I=V/R. An inductive, or clamp on ammeter measures the magnetic field and using more complex calculations displays the current, typically on a digital display.
The light bulb creates light when electric current flows through the filament. Electric current is the movement of charges. It takes electric current to run an electric …motor.
An Ammeter is used to measure electrical current, which is measured in Amperes (or Amps).
Current is a simple descriptor, I was taught to always use it in school as leaving it off was an error. For instance you cannot say A for AC (Alternating Current) as A is ampe…rage.
The easiest way to answer your question is to point out that every device you own or use, which you plug into the wall or which contains a battery, makes available to you …some use of electrical current. Whatever you use each of those devices for is a use of current electricity.
Electricity has been found to be the best thing to use for an electric current.
The letter "I" (capital "i"). Lowercase "i" is also used sometimes (for instantaneous current).
Electrical current is measured in Amperes which is abbreviated toamps. When dealing with formulae the letter I is used to representcurrent, for example: Power = Voltage Ã… Current = volts Ã amps = V Ã I Small currents in electrical engineering use the lower case i; thiscan cause confusion with the lower case i that mathematicians usefor â-1, so they use j for â-1 instead.
unit used for electric current is ampere
Here are a few examples... - The electrical current is monitored. - The current of electricity is measured in volts. - The electrical current of telephone wiring is 82 volt…s. They may not be worded the same, but they have the same initial meaning.
Thier electrical current will be from the solar energy converter to electricity.
ammeter ...the branch in which current is to be measure..ammmeter is connected in series in that branch..
Anemometers, employed for measurement of wind speed, often take thefamiliar form of the spinning cups or a propellor-like windmill,but can indeed also use electrical current a…s one measurementmethod. With these hot-wire anemometers, measured changes incurrent, voltage or temperature can be used to accurately andquickly derive wind speed.
