Pramit Bhattacharya EE 202 Sec R_1 Homework 1 01/17/10 1) Ohm’s Law states that in electrical circuits the current through a conductor between two points is directly proportional to the potential difference (voltage) and inversely proportional to the resistance between them. I = V/R V = 1.25 V, R = 1 KΩ So, I = 1.25 V/(1000 Ω) = 1.25*10
