I'm really new to circuits so any help would be nice!!

1. The problem statement, all variables and given/known data
1) derive the basic properties of a simple series circuit.
2) derive the basic properties of a simple parallel circuit.

2. Relevant equations
n/a

3. The attempt at a solution
1)a)the current through a circuit element is the same throughout the circuit.
b)the sum of the resistance is equal to the total resistance in the circuit.
c)the sum of the voltages across each circuit element is equal to the total voltage of the source.
d)i dono
e)i dono

2a)the voltage across a circuit element is the same as the source throughout the circuit
b)the sum of the current through each branch is equal to the total current
c)1/Rtotal = 1/R1 + 1/R2 . . . + 1/Rn
d)i dono
e)i dono

there's supposed to be 2 more properties for each. and i have no clue what they are. I've looked through my text and through internet sources but i can only find 3.
