The most common fault that makes it obvious for you to think it is burnt is the capacitor. With the smell, and sometimes the liquid electrolyte from the busted capacitor draining through. If you are lucky enough and it’s just … Continue reading →

If a device rated for 5v is connected to a 12v supply, some of the components may get burnt or damaged due to over current. If the applied voltage to equipment is more than its maximum rated voltage, the equipment … Continue reading →

USB-C supports older versions of the HDCP copy protection standard, but cannot yet handle the latest HDCP 2.2 standard. Only HDMI can currently do that. You’ll still need HDMI cables to support “legacy” devices which weren’t built with USB-C ports … Continue reading →

➨Choppers are inadequate due to unsteady voltage and current supply. ➨Disadvantages of fly-back type: More EMI due to gap, More ripple current, More input/output capacitance, higher losses etc. What are the advantages of chopper? DC chopper device has the advantages … Continue reading →

If it’s a DC motor used as a generator, it will produce DC. The coils in the armature carry AC, but the commutator rectifies that to DC at the terminals. magnetic field. Even a generator, DC or AC, cannot produce … Continue reading →

The easiest way to replace a cigarette lighter with USB is to just toss the lighter portion and plug in a low profile 12V USB adapter. Some 12V USB chargers are big and bulky, but there are a number of … Continue reading →

Unlike AC power, 24V DC does not require the use of personal safety equipment. Maintenance can be performed safely on energized circuits. If an accident occurs that exposes 24V DC wiring, there is no potential for personnel injury. Is 24V … Continue reading →

Overcharging destroys batteries quickly. Undercharging destroys batteries too, but more subtly as the battery stratifies and will no longer maintain a charge. How long should you charge a 6 volt battery? For 6v batteries, the first charge should be 10 … Continue reading →

Notice that in both AC electricity and DC electronics, there is a black wire. But in AC electricity the black is hot (“positive”) whereas in DC electronics black is for negative. What color is positive AC? redWire Colors for DC … Continue reading →

Yes, it is safe as long as you don’t short out the battery. The battery’s voltage is not an issue, as almost all routers contain an internal regulator, especially when they do not use a lower voltage power supply. However, … Continue reading →

Inverter AC runs on AC current, not on DC current, and it doesn’t have any battery in it or with it. Here, the term “inverter” make confusing for some people. Because the device inverter is used to convert DC power … Continue reading →
