Question

Wat is actually charge and wht is current . Reply immediatly

Answer 1

Charge is an inherent property of matter. Current is the rate change of charge i.e. \[I=\frac{dQ}{dt}\]

Answer 2

Electric charge is an intrinsic physical property of matter which causes it to experience a force when near other electrically charged matter.

Electric charge is of two types - positive and negative.

Two positively charged substances/objects experience a mutual repulsive force, as do two negatively charged substances/objects.
A positively charged object and a negatively charged object experience an attractive force.

The SI unit of electric charge is the coulomb (C).

Answer 3

Electric current is the ordered flow of electric charge through a medium.

Generally we speak of current through a wire. This is typically carried by moving electrons in a conductor such as a metallic wire.

Current can also be carried by ions in an electrolyte, or by both ions and electrons in a plasma.

The SI unit for measuring the rate of flow of electric charge is the ampere (A), which is charge flowing past a point at the rate of one coulomb per second.
Q
so I = -----
t
The device used to measure electric current is called an ammeter.

Answer 4

ok
charge is defined as the integral multiple of passive unit of charges.. i.e. Q=(+/-)ne
where, n= no of electrons, e= charge per electron = 9.1*10^(-18)coulomb
and
current is the rate or flow of charge.. i.e I=dQ/dt its unit is ampere in SI
