In the circuit shown in FIG. 7, the power supply voltage remains constant. Closing key S, the circuit to work, after a period of time there are shown two meter numbers change,
In the circuit shown in Figure 7, the supply voltage remains the same. Closed key S, the circuit works normally, after a period of time there are two meters of the indication changes,
In the circuit shown in Fig. 7, the supply voltage remains constant. When the key s is closed, the circuit works normally. After a period of time, the indication of two meters changes,<br>
