There are several undefined terms which we should keep in mind. They are consistent, because they deal with two different situations:
(i) says that the given two points A and B, there is a point C lying on the line in between them;
(ii) says that given A and B, we ca take C not lying on the line through A and B.
These ‘postulates’ do not follow from Euclid’s postulates.
However, they follow from axiom stated as given two distinct points; there is a unique line that passes through them..i
• The flow of charge at per unit time is called electric current.
• The charge passing per unit time through a given place is the magnitude of electric current at that place.
• SI unit of current is Ampere (A).
• If one coulomb of charge passing through a place in one second, then the current is said to be one ampere.
✧ Mathematical term
• I = Q/t
here,
I is the current
Q is the charge
t is the time.
You can also use Ohm's Law to Calculate the Electric current.
• V = IR
where ,
V is the Potential Difference/Voltage.
I is the Electric Current.
R is the Resistance .
