I_{1}

I_{2}

? (A)

\mathrm{I}_{1}

is greater, because it has more resistance. (B)

\mathrm{I}_{2}

is greater, because it has less resistance. (C)

\mathrm{I}_{1}

is greater, because of charge conservation. (D)

\mathrm{I}_{2}

is greater, because of energy conservation. 17. What is the current

I_{1}

? (A) 1 mA (B) 3 mA (C) 4 mA (D) 12 mA 18. Which of the following changes would increase the value of

\mathrm{I}_{1}

? (A) Remove

\mathrm{R}_{3}

and the branch containing it. (B) Replace

\mathrm{R}_{2}

with another 6000 Ohm resistor. (C) Add an 8000 Ohm resistor in parallel with

\mathrm{R}_{2}

and

\mathrm{R}_{3}

. (D) Rewire the circuit, putting all three resistors in series.
