This circuit uses a half cycle of AC power Voltage , for feed give with AC Lamp. The part again a half cycle that go to give with capacitor C1. For build voltage to feed reach a pin G of SCR. When arrive at the dot at firing angle SCR will lead the electric current [...]

This be Lamp Flasher again model apply to Lamp small-sized 6 Volt, by use the principle Amplifier Circuit that use transistor 2 pcs. By have regenerative feedback send pulse of current 60 mS. Which there is tall size arrives at many amp change low voltage lamp. For brightness rate of something flasher , The tall [...]

Some applications require a circuit to indicate that a battery’s voltage has fallen below a certain value. However, if you don’t frequently check the indicator, the low-battery indicator itself can easily discharge the battery. The circuit in Figure 1 indicates when the battery voltage has dropped below a preset value. The circuit draws less than [...]
