Electrical Circuit Analysis Lab

In this lab you will be assigned and given 4 resistors. You will need to identify the resistor values and the tolerances on those values based on the colour codes painted on the resistors. They are to be connected according to the circuit diagram below on a breadboard. You will apply the specified electrical potential and measure V3.

Pre Lab

• resistor colour codes - do research to identify the value of the resistors and their tolerances from the colour codes on the resistors.
• breadboard (instructions for use of breadboard here)
• each student will be assigned specific resistors for R1 to R4 and a specified V1 (supply voltage)
• students should complete a preliminary calculation of expected power dissipated in each resistor to ensure it is below 1/4 W. (error propagation not required in this step)
• electrical safety
• equipment information

Lab

• Build circuit and measure V3 (voltage across R3)
• Verify whether the measured value falls within the theoretical value. (emphasis error analysis)

What to Hand In

• Lab Report
  • must also include schematic (computer drawing available in room 205 software called Tina) (and may include simulated results)(to generate schematic images check instructions here)
