Parallel Circuits

Wire the circuit in figure 1 with the same resistors. Take readings in different places shown in figure 2 by
moving the multimeter. Make a table like the one below, calculating R using Ohm’s Law for the last
column. 

b. How is the total resistance related to the individual resistances? Explain what you think is happening.
c. Look up the mathematical relationship for finding total resistance in a parallel circuit. Show that your
data fits the equation
