Measuring Resistance parallel combination

For parallel combination of resistors, this relation exists between the effective resistance R and the components: \frac{1}{R} = \frac{1}{R_1} + \frac{1}{R_2} + ⋯

Objective

Measure the resistance of parallel combination of resistors. Values 560, 1000 and 2200 Ohms are available with the kit.

Procedure for two resistors

  • Measure the resistances separately.
  • Connect them as shown in the figure.
  • Observe the value shown on the right side panel.
  • Compare the values with calculated results.
  • Repeat the experiment with different resistors.
