Electric current  class-10 Electric Current: The flow of electrons across a cross section of a conductor is known as Electric Current, Electric current is carried by moving electrons through a conductor.  What is electric current Or Define Electric current The rate of flow of electric charge through any section of a conductor is known as electric current. It is denoted by letter I.   What is the expression of electric current? If a net electric charge (Q) flows through a cross section of conductor in time t, then: Electric Current ( I ) = Net charge ( Q ) Time ( t ) Electric Current ( I ) = Net charge ( Q ) Time ( t ) Or,  I = Q t I = Q t Where I is electric current, Q is a net charge and t is a time in second. What is the SI unit of Electric current? The SI unit of Electric current is Ampere. Define 1 Ampere. if 1 coulomb of electric charge flows through a cross section for 1 second, it would be equal to 1 ampere. Electric Current ( I ) = Net charge ( Q ) Time ( t )...

Ohm's law Ohm's law shows the relationship between the voltage (V), Current (I) and resistance (R) Who gave ohm's law?  Georg Simon Ohm, a German physicist invented ohm's law What is the definition of ohm's law? Or State ohm's law  Ohm's law states that the current passing through a conductor is directly proportional to the potential difference across its ends. If I is the current flowing through a conductor, when the potential difference across its end is V then V∝I or I∝V ⇒V=IR. What is the application of ohm's law? or  what is the main advantage of ohm's law ? The main advantage of ohm's law is to determine either voltage, current or resistance when we know the values of other two. What are the limitations of ohm's law?  The law is not applicable to unilateral networks such as diode, transistor etc.  This law is not applicable to non linear elements.  This law is only true, when the temperature and other physical factors remain constant.
