Quick Quiz 28.4 With the switch in the circuit of Figure 28.5 closed (left). there is no current in R. because the current has an alternate zero-resistance path through the switch. There is current in R, and this current is measured with the amme- ter a device for measuring current) at the right side of the circuit. If the switch is opened (Fig. 28.5. right). there is current in Ry. What happens to the reading on the ammeter when the...
