Overcurrent Earth Fault Protection: Overcurrent Earth Fault Protection - Earth-fault protection can be provided with normal overcurrent relays, if the minimum earth-fault current is sufficient in magnitude. The magnitude of…
Instantaneous Overcurrent Relays: If the relay operates instantly without any intentional time delay, this characteristic can generally be satisfied by a relay of the non-polarized attracted armature type. This relay…
LED Seven Segment Display: The arrangement of a LED Seven Segment Display is shown in Fig. 20-6(a). The actual LED devices are very small, so, to enlarge the lighted surface,…
Diode Applications Articles: Half Wave Rectifier Circuit: A basic diode Half Wave Rectifier Circuit is shown in Fig. 3-1(a). An alternating input voltage is applied to a single diode connected…
Switching Regulator Operation: A Switching Regulator Operation can be thought of as similar to a linear regulator, but with the series-pass transistor operating as a switch that is either off,…
IC Linear Voltage Regulators: 723 IC Regulator - The basic circuit of a 723 IC Linear Voltage Regulators in a dual-in-line package is shown in Fig. 17-20. This IC has…
Transistor Series Voltage Regulator: When a low power zener diode is used in the simple Transistor Series Voltage Regulator, the load current is limited by the maximum diode current. A…
Colpitts Oscillator using Op Amp: The Colpitts Oscillator using Op Amp circuit show in Fig. 16-4 is similar to the op-amp phase shift oscillator, except that an LC network is…
