20.2 Kirchhoff's Laws

A PowerPoint going through the following outcomes for the CIE A-Level physics syllabus:

a) recall Kirchhoff’s first law and appreciate the link to conservation of charge
b) recall Kirchhoff’s second law and appreciate the link to conservation of energy
c) derive, using Kirchhoff’s laws, a formula for the combined resistance of two or more resistors in series
d) solve problems using the formula for the combined resistance of two or more resistors in series
e) derive, using Kirchhoff’s laws, a formula for the combined resistance of two or more resistors in parallel
f) solve problems using the formula for the combined resistance of two or more resistors in parallel
g) apply Kirchhoff’s laws to solve simple circuit problems

Feedback would be much appreciated.
