1 Ohm’s Law To better understand the applications of Ohm’s Law, we experimented with variable resistances with a fixed voltage. Using a Digital Multi-meter and a Ammeter, we measured the voltage across a known resistor in series as well as the current out of the resistor. Then by graphing the data, we can see the linear correlation between the voltage and the current in a circuit with varying resistance. We also experimented with a light bulb replacing our known resistor, and comparing the data taken with the light to that of the resistor. Exercise 1: Measuring the Current and Voltage for a Nominal 100 Ω Resistor The circuit is set up in series as shown here. The power supply is set to 5 volts. The Digital Multi-meter, denoted by a circled V, is attached in parallel to the known resistor because voltage in parallel is conserved, allowing us to measure the voltage across the resistor. The Ammeter, denoted by a circled A, is attached in
