1
Q
Kirchoff’s 1st Law
A
Sum of current entering a junction = sum of current leaving a junction
2
Q
Kirchoff’s 2nd law
A
EMF in a series circuit = sum of pds across each component in the circuit.
3
Q
Resistivity
A
R=ϱL/A, so ϱ = RA/L (R is rlaaaa …)
4
Q
Conductivity
A
G = σA/L, so σ = GL/A ( Gee, Sally!)
