Question

Answer it!!!
⚠️Don't give unusual answers!!​

Answer 1

Step-by-step explanation:

• 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 .

Answer 2

$\underline{\pink{\bf{\purple{\dag}\:Answer:-}}}$

There are several undefined terms which we should keep in mind. They are consistent, because they deal with two different situations:

$\sf\red{⟶}$(i) says that the given two points A and B, there is a point C lying on the line in between them;

$\sf\red{⟶}$(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.
