ELCT 363: Intro. to Microelectronics Dr. Mandal/Fall 2011 Lecture 4; Slide2 2. Basic physical and mathematical concepts (a) Holding resistance constant, how does increasing current in a circuit affect voltage? V = IR, If R is constant, then V is directly proportional to I, therefore Voltage increases with increased current
