Electric current is defined as a stream of charged particles—like electrons or ions—moving through a conductor or space. It measures how fast electric charge flows through a medium over time. The symbol for electric current in formulas is “I” or “i”. The unit for current is the amper...
In this type of electric current, direction is always same. Theelectric current generatedfrom a cell orbatteryis DC. Due to the same direction of Direct Current, itsfrequencyis ZERO. In DC Current one end is Positive (+) and the other end is Negative (-). DC Current Symbol Alternative C...
Types of Electric Current Table of Contents What is the SI Unit of Current? The SI unit of current is ampere (Unit Symbol=A). Formula: 1 Ampere = 1 Coulomb of charge passing a given point per second. Read:How is Electricity Generated, Transmitted and Distributed?

Electric current is the flow of electric charge. The unit of electric current is theampere,which we give the symbolA. A current of1 ampere,or1 A,is equivalent to1 coulombof charge passing a point in onesecond,or1 C/s. There are two different types of electric current that are used in...

Units of Electric Current Description Examples Description Electric current is a base dimension in the International System of Units. The SI unit of electric current is the ampere , which is defined as the constant current that, if maintained in two...
When you hook up wires to the terminals of a battery, charge can flow and a complete path called a circuit is formed. This flow of charge is called acurrent.The symbol for current is the letter I and the unit of measurement is called the ampere. The higher the current running through ...
