1.An instrument used to measure the flow of current in a circuit is called an ammeter.

2.Since the voltage drop across the ammeter is negligible, essentially all the test voltage appears across R.R

3.If the component or material breaks down, all the voltage would be applied to the ammeter's input, possibly destroying it.穿

4.To start with, you need to break the circuit so that the ammeter can be connected in series.

5.The guard can be used to isolate the high impedance input lead of the ammeter from leakage current due to voltage sources.线

6.To measure the offset of a switch card, connect the output of the card to a pico ammeter or electrometer.

7.The protection circuit should be enclosed in a light-tight shield. The shield should be connected to the low of the ammeter.

8.Since the voltage burden of the electrometer ammeter or picoammeter is less than 1mV, the diodes won't conduct.1mV,

9.To see how changes in source capacitance can affect noise gain, let's again refer to the simplified ammeter model in Figure 2-15.2-15

10.Connect the battery and ammeter to the starter as shown in the illustration.
