Measuring Resistance parallel combination
=========================================

For parallel combination of resistors, this relation exists between
the effective resistance :math:`R` and the components:
:math:`\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.
