Voltage: Ohm's Law and Kirchhoff's Rules Ohm's Law and Kirchhoff's rules is fundamental for the understanding of dc circuit. This experiment proves and show how these rules can be applied to so simple dc circuits. INTRODUCTION In the theory of Ohm's Law, voltage is simply proportional to current as illustrated in the proportionality, V=RI. As shown in this relation, V represent voltage which is the potential difference across the two ends of a electrical conductor and between which an electric current, I, will flow. The constant, R, is called the conductor's resistance. Thus by the Ohm's Law, one can determine the resistance R in a DC circuit without measuring it directly provided that the remaining variable V and I is known. A resistor is a piece of electric conductor which obeys Ohm's Law and has been designed to have a specific ....
