Chapter 28, Problem 28.3QQ
With the switch in the circuit of Figure 27.6a open, there is no current in R2. There is current in R1, however, and it is measured with the ammeter at the right side of the circuit. If the switch is closed (Fig. 27.6b), there is current in R2. What happens to the reading on the ammeter when the switch is closed? (a) The reading increases. (b) The reading decreases. (c) The reading does not change.
Figure 27.6 (Quick Quiz 27.3) What happens when the switch is closed?
