Series-Parallel Circuits
___________________________________________________________________
Objective: To investigate the properties of series-parallel circuits
Components Required:
3 x 1-kΩ resistor
1 x breadboard
Procedure:
⦁ Build a series-parallel circuit with Vs = 6.0 V and three 1-kΩ resistors where R1 is in series with R2 // R3
⦁ Connect the negative terminal of the supply to the Earth ground
⦁ Use the worksheet provided below to calculate the theoretical circuit voltages and currents
⦁ Measure the circuit parameters and calculate the percent errors
