Intensity.
"I" is the letter typically used to represent current in electrical equations.
the letter used is "I"
The letter "I" (capital "i"). Lowercase "i" is also used sometimes (for instantaneous current).
The letter used to represent current in equations is "I." This designation comes from the French term "intensité de courant," which translates to "current intensity." In electrical equations, current is typically measured in amperes (A).
The letter L (written in uppercase) is used as a symbol for inductance. If you mean the letter I (uppercase i), that refers to current.
A multimeter is a common instrument used to measure electrical current. It can measure current, voltage, and resistance in electrical circuits.
Electrical current is measured using an ammeter.
An Ammeter is used to measure electrical current, which is measured in Amperes (or Amps).
A device used to adjust the flow of electrical current is called a resistor.
The electrical symbol for a continuous or r.m.s. currentis an italic, upper-case, letter I. The symbol for an instantaneous value of current is an italic, lower-case, letter i.The symbol for its SI unit of measurement, the ampere, is an upright, upper-case, letter A.
AC, alternating current is used to power electrical outlets in the U.S..
The uppercase letter "I" is used for DC current, or for the average current; the lowercase letter "i" is used for instantaneous current.
