Physics Challenge Question 21: Resistors
Due in class Tuesday 3/31/2009
3
6V
2
5
Part 1
Which resistors are in series, and which ones are in parallel?
Part 2 (1 point)
Find the effective resistance of the circuit drawn above.
Part 3 (1 points)
Find the voltage drop over each resistor, as well as the current flowing through
each.
Part 4 (1 point)
What happens if you keep adding infinitely many 1  resistors in parallel to the two
already connected in parallel? What will the circuit’s effective resistance be now?
What are the voltage drop over and the current through each of these 1 
resistors?
Part 5 (1 point)
What happens if you keep adding infinitely many 1  resistors in series to the
circuit? What will the circuit’s effective resistance be now? What are the voltage
drop over and the current through each of these 1  resistors?
