Total Resistance in Series Vs Parallel Circuits
1) Find an equation for calculating the total resistance in a series circuit and put this onto a word document.
2) Find an equation for calculating the total resistance in a parallel circuit and put this onto a word document.
3) Calculate the total resistance and current (using Ohm’s Law) for the following if the voltage is constant at
30V:

4) Enter the Resistor Number and Current value for The Series and Parallel circuits into an excel document with
the following column headings
Resistor number
Series Current (Amps)
Parallel Current (Amps)
5) Once the data is entered, produce a line graph of the information (called a scatter graph) – you should end
up with the two graphs on one graph.
6) Copy this graph to the word document and email this word document to Mr Bowen:
