Matthew Malek Lab Partners: Jon and Christina Lab #8 DC Circuits (series and parallel) Objectives: To verify the equations that relates total current, voltage and resistance with individual values in a series and parallel dc circuit. Theory : In a series circuit the current throughout is constant, while both voltage and resistant will be added to themselves to find the sum of each. In a parallel circuit the voltage is constant, while you add the currents to themselves to find total current and resistance is 1 over the resistance of each added together. Series – Parallel - V = V1 + V2 + V3 V = V1 = V2 = V3 I = I1 = I2 = I3 I = I1 + I2 + I3 R = R1 + R2 + R3 R = 1/R1 + 1/R2 + 1/R3 Procedure : Use jumpers to build a series circuit and test the current voltage

Build a parallel circuit and retest each point and record the values for current, voltage, and resistance. Then use the equations in the theory to prove with your data. Conclusion After recording all the values and doing all the equations we see that these equations are correct. In a series circuit, when you add all the resistances you get the total resistance. The same is true for voltage while current is constant throughout the circuit. In the parallel circuit, when you add all the currents up you get the total current. The voltage is the same throughout the circuit, while the total resistance it the sum of the reciprocal of all the resistances....
