A voltage at a power terminal in the control circuit 8 rises by the charging of a capacitor C1 and the TR Q2 keeps the on-state. Thus, even if the switch 10 is restored to the off-state, the line closing state is kept remained. When the talking with the opposite side is finished ...

In closed loop control schemes (such as that implement by CISCO by way of their ForeSightcongestion avoidance algorithm), the rate at which data is allowed to enter the network on each virtual circuit is adjusted in response to the utilization of the network trunks along that data path at tha...
For instance, the following diagram shows a normally-open pushbutton switch controlling a lamp on a 120 volt AC circuit (the “hot” and “neutral” poles of the AC power source labeled L1 and L2, respectively): We can tell this switch is a normally-open (NO) switch because it is draw...
* Capable measurement of currents: DC, AC,pulse with galvanic isolation between primary circuit and secondary circuit. Advantages * Easy installation * Can be customized * No insertion losses * Low power consumption * Wide current measuring range ...
In the circuit at right the switchShas been closed for a long time, so no currents are changing.(Therefore the capacitor's charge is constant. What does that tell you about the current through it?). a)Draw an arrow for each curr...
