Consider positive and negative charges all moving horizontally with the same speed through the four regions in Figure 17.2. Rank the magnitudes of the currents in these four regions from lowest to highest. (Ia is the current in Figure 17.2a, Ib the current in Figure 17.2b, etc.) (a) Id, Ia, Ic, Ib (b) Ia, Ic, Ib, Id (c) Ic, Ia, Id, Ib (d) Id, Ib, Ic, Ia (e) Ia, Ib, Ic, Id (f) None of these

(Quick Quiz 17.1)
Given Info: Positive and negative charges all moving horizontally with the same speed through four regions in figure 17.2
Current is the rate of flow of electric charge. Negative charge moving towards left is same as positive charge moving towards right.
Use the principle of addition of charges to calculate the amount of charge flowing.
- (a) Positive 3 charges moving towards right and negative 2 charges moving towards left
- (b) Positive 3 charges moving towards right
- (c) Positive 3 charges moving towards right and negative 2 charges moving towards left
- (d) Negative 2 charges moving towards right
