I=n*V*S*e(1)
n=N/S*L N=q/e n=q/S*L*e(2) Подставим 2 в 1
I=q*V/L=3*0,5/1=1,5 A

(1) Undergraduate education is the post-secondary education previous to the postgraduate education. It includes all the academic programs up to the level of a bachelor’s degree. Most undergraduate education (other than the University of Buckingham and BPP University College, both private institutions) is state-financed with some tuition fees to cover costs.
(2) Those who study in England know of the hierarchy within the universities. The Russell Group, which is a network of 24 British public research universities, contains some of the most prestigious universities in the country. This prestigious group includes universities such as the University of Birmingham, the University of Oxford, the University of Cambridge, and the University of York. All of these are well-known universities and many people, both citizens of Great Britain and international students, aspire to attend university at one of these schools.
(3) Most syllabi are set by the universities which are offering them, and are not controlled by the government. The only exception to this is teacher education programmes. Most countries have specific regulations for their teachers, so this is not any different than studying teaching in your home country. Because of their strict regulations and high standards for teacher education programs England is considered to have some of the best teacher education programs in the world.
(4) Even though the syllabi are set by universities, the Office for Fair Access is responsible for ensuring the fair admission procedures of each university. This office was created so that everyone who wishes to attend university in England has the ability to do so. They also promote fair access to higher education even for those who are attending university as international students. Fair access also includes those of different cultures, different races, different nationalities, and those who have disabilities.
