Answer:
Higher current is normally achieved by faster moving electrons.
Explanation:
- Current is solely not the speed of the electric charges, but speed of the electrons is one of the factors that current depends on.
- Current is the net charge flowing per unit time.
- Current can be represented by:
I=v×e×N×A
where,
I= current
e= electric charge
v= speed of electrons
N=no. of free electric charges per volume
- The unit of current is Ampere, represented by A. It is flow of 1 coulomb of charge in 1 second.
Constantine I helped to socially and politically unify the early byzantine empire by tolerating and even promoting christianity.
From the Hooke's law , the extension force of an elastic material is directly proportional to the extension.
That is, F = k e, where F is the force , k is the constant and e is the extension
F = 10 × 10 = 100 N
e = 1mm or 0.001 m
Hence, k = F/e
= 100 N/ 0.001
= 100000 N/m or 100 N/mm
Oh ya the correct answer for this is B I think because structure B
If this is a long straight wire, then you probably mean:
B = μ₀I/(2πd)
