Purpose The purpose of the lab was to understand how voltages and currents are generated and measured in the laboratory, and to investigate how voltage and current are related in resistors. Description The apparatuses used in the experiment depended on what was being tested. Various circuits were constructed for lab, including, but not limited to, circuits in series, parallel circuits, circuits with voltage meters attached, as well as circuits using alternative power sources ( eg.amplifiers) Theory No matter what kind of circuit is created, ohm's law can be used to find voltage, current, or resistance. Ohm's Law is given by the equation V=IR; where v is the voltage (in volts), I is the current (in amperes), and R is the resistance (in ohms). Each variable is algebraically summed and then used in the equation; for example, if there are two resistors in series in a given circuit (R1, R2), then the value for R used in ohm's law will be the sum R1+R2. Current is theoretically constant throughout a circuit.
