What is the electrical resistance? Course Title: Basic Electricity and Ohms Law Course description: Introduces the student to basic electricity with an emphasis on Ohms Law. Advertisement. For much of our world to operate, we need electrical energy. Where R is electrical resistance, V the potential difference, I is the electric current. Find the resistance of a circuit that draws 0.06 amperes with 12 volts applied. According to Ohm’s law, there is a linear relationship between the voltage drop across a circuit element and the current flowing through it. Based on the table, the relationship between V, I and R is the value of R inversely proportional to V and I.
