To measure currents in Figure 21.47, you would replace a wire between two points with an ammeter. Specify the points between which you would place an ammeter to measure the following:

(a) The total current; 

(b) The current flowing through R₁; 

(c) Through R₂;

(d) Through R₃. Note that there may be more than one answer to each part.
