The DC Circuits lab was conducted so the idea of Ohm’s Law would become clear to use and we would be able to use it easily when the time comes. Ohm’s Law is defined as V=I*R, where V=Voltage (V), I= Current (I), and R= Resistance (R). The three parts of Ohm’s Law are measured in Volts for Voltage, Amps for Current, and Ohms for Resistance. By using this law we will be able to calculate volts, amps, or ohms, depending on what is given and what the variable is. There were five different setups to the experiment and each one consisted of different variables being added or removed from the setup. Trial 1: The setup is taken from the lab manual. Trial 1: Data Voltage (V, 20V) Distance (cm) 0.47 5 1.14 8 1.83 11 2.76 15 3.89 20

Trial 2: The setup is taken from the lab manual Resistor= 47 Ohm’s +/- 10% (actual) Trial 2 Data: Voltage (V) Current (I, milliamps) 0.41 7.6 1.13 20.9 2.05 37.7 3.32
