Simple Resistor Circuits-Voltage Drop All the resistors in the circuits below are identical at 2 each. The batteries are ideal with voltages of 6 or 12 volts as shown. All connecting wires have negligible resistance. Rank the voltage at the upper right-hand corner relative to the ground- Place the highest voluage first and the lowest voltage last. 12 V 6 V 12 V 6 V 12 V 6 V Highest 2 3. Or, all of the voltages are the same. Please carefully explain your reasoning. How sure were you of your ranking? (circle one) Basically Guessed Very Sure 10

Explanation / Answer

For A

Req =2+2+2 =6 ohms

I=12/6=2 A

VA=2*(2+2)=8 Volts

For B

VB=6 V

For C

VC=12 V

For D

I=6/(2+2)=1.5 A

VD=2*1.5=3 V

For E

I=12/(2+2)=3 A

VE =3*2=6 V

For F

I=6/(2+2+2)=1 A

VF =(2+2)*1=4 Volts

Ranking C>A>B=E>F>D
