The Ampere and the Coulomb (units of current and charge)

Question 1

Electric Current is defined

Answer 1

as charge passing a point per unit time, symbolized as
Q
I=—–
T

Question 2

Unit of current is the ampere (A)

Answer 2

with one milliampere (mA) equal to one-thousandth of an ampere and is measured by an ammeter.

Question 3

Unit of charge is the coulomb (C),

Answer 3

defined as the charge passing a point when a steady current of 1 ampere flows for 1 second (1C=1As).
