# Circuit Behavior

Any circulating flow constitutes a circuit. Learn how to model the logic boards in your computer, the flow of nutrients in your blood, or the daily fluctuations in the temperature of your house.

# Series and parallel resistors

Given $$R_1 = 3.0\ \Omega,$$ $$R_2 = 6.0\ \Omega,$$ $$R_3 = 4.0\ \Omega,$$ $$R_4 = 8.0\ \Omega,$$ $$R_5 = 6.0\ \Omega,$$ $$R_6 = 3.0\ \Omega,$$ $$R_7 = 6.0\ \Omega$$ and $$R_8 = 12.0\ \Omega,$$ what is the approximate overall equivalent resistance?

In the circuit above, $$V=9.6\text{ V},$$ $$R_1=2\ \Omega,$$ $$R_2=9\ \Omega,$$ and $$R_3=18\ \Omega.$$ Find the current through $$R_3.$$

Given $$R_1 = 5\ \Omega$$ and $$R_2 = 10\ \Omega,$$ what is the overall equivalent resistance?

Given $$R_1 = 5.0\ \Omega,$$ $$R_2 = 4.0\ \Omega,$$ $$R_3 = 2.0\ \Omega,$$ $$R_4 = 6.0\ \Omega,$$ and $$R_5 = 8.0\ \Omega,$$ what is the approximate overall equivalent resistance?

Given $$R_1 = 9\ \Omega$$ and $$R_2 = 18\ \Omega,$$ what is the overall equivalent resistance?
