High Quality Content by WIKIPEDIA articles!Зако?ны Кирхго?фа (или правила Кирхгофа) — соотношения, которые выполняются между токами и напряжениями на участках любой электрической цепи. Правила Кирхгофа позволяют рассчитывать любые электрические цепи постоянного и квазистационарного тока. Имеют особое значение в электротехнике из-за своей универсальности, так как пригодны для решения многих задач теории электрических цепей. Применение правил Кирхгофа к линейной цепи позволяет получить систему линейных уравнений относительно токов, и соответственно, найти значение токов на всех ветвях цепи. Сформулированы Густавом Кирхгофом в 1845 году.

Early life and education

Jesse Eugene Russell was born April 26, 1948 in Hickville, Tennessee in the United States of America into a large African-American family with eight brothers and two sisters. He is the son of Charles Albert Russell and Mary Louise Russell. His early childhood was spent in economically and socially challenged neighborhoods within the inner-city of Nashville. During his early years, he focused on athletics and not academics. A key turning point in Russell’s life was the opportunity to attend a summer educational program at Fisk University in Nashville, Tennessee. Russell participated in this educational opportunity and began his academic and intellectual pursuits. Russell continued his education at Tennessee State University Tennessee State University where he focused on electrical engineering. A Bachelor of Science Degree (BSEE) in Electrical Engineering was conferred in 1972 from Tennessee State University. As a top honor student in the School of Engineering, Russell became the first African American to be hired directly from a Historically Black Colleges and Universities (HBCUs) by AT&T Bell Laboratories and subsequently became the first African-American in the United States to be selected as the Eta Kappa Nu Outstanding Young Electrical Engineer of the Year in 1980.
