Three Resistors with Resistances Of $2.0 \Omega , 6.0 \Omega$ , And

Multiple Choice

Three resistors with resistances of $2.0 \Omega , 6.0 \Omega$ , and $12 \Omega$ are connected across an ideal dc voltage source $V$ , as shown in the figure. If the total current in the circuit is $I = 5.0 \mathrm {~A}$ , what is the current through the 12- $\Omega$ resistor?

A) $5.0 \mathrm {~A}$
B) $1.7 \mathrm {~A}$
C) $0.75 \mathrm {~A}$
D) $0.56 \mathrm {~A}$
E) $2.5 \mathrm {~A}$
