They both are types or categories of nitrogen containing bases present in nuclei acids of DNA and RNA.
Purines are 2 Ring or Carbon Ring, Nitrogen containing bases. That consist of these 2 rings next placed next to each other. These examples include - Adenine and Guanine.
Pyrimidines are 1 or single Ring Nitrogen containing structures. There are 3 nitrogenous bases that are categorized as pyrimidines. Cytosine, Thymine, and Uracil.
Do you have a book about it? or if you have a dictionary?

Explanation:

PART A)
Equivalent resistance in series is given as
now we have
PART B)
Here in order to find the current in the circuit we can use ohm's law
here we have
V = 24 Volts
R = 23 ohm
PART C)
Now in series circuit all branches of resistance connected to each other
so here no division of current
hence current in all resistors will be same
so we have
