Summer 2020 PHYS 314 Test 3 (Written Part) Name (Print) ______________________________
1. In the above circuit determine the cu
ent through the 3 Ohm resistor. Draw each subsequent
circuit diagram as you simplify.
I = ________________________________________________
2. In the table provided below enter the values of cu
ent and through and voltage across each
esistor. Include units in each cell, and leave answers in terms of fractions.
24 Ω 3 Ω 4 Ω 12 Ω 5 Ω
Now assume that a grounding wire has been placed on the lower-right corner of the original circuit, so
the potential between the 3V and 3 Ohm resistor is 0V. Find the potential at each other corner and in
etween the 5 Ohm resistor and 4/12 Ohm combination.
