The physical quantity which is dependent on other physical quantity or which is derived from other physical quantity is called derived physical quantity.
Ex :
Electric charge(quantity of electricity unit-coulomb),
electric potential difference,electromotive force (unit- v )
electric resistance(unit-ohm),
electric conductance(siemens),
electric field strength(unit -volt per meter),
electric charge density(unit -coulomb per cubic meter),
electric flux density(unit -coulomb per square meter),
current density(unit -ampere per square meter)
These are some derived quantities related to electric current.
