Transistor-transistor logic. Transistor-transistor logicTransistor-transistor logicTransistor–transistor logic (TTL) is a logic family built from bipolar junction transistors. Its name signifies that transistors perform both the logic function (the first “transistor”) and the amplifying function (the second “transistor”), as opposed to resistor–transistor … Continue reading →

Laptop chargers have two parts: a transformer and a power cord. The transformer is the brick that converts the current from your power outlet from AC to DC, and the power cord connects the charger to the outlet. Over time, … Continue reading →

Companies in Europe realized that supplying power at 220 volts instead of 110 volts would be cheaper. At a higher voltage, electric companies can deliver the same power with less current – picture a narrow stream flowing quickly compared to … Continue reading →

Improper use of flexible and temporary wiring such as extension cords, multi-outlet adapters, uninterruptible power supplies, and power strips can present both fire and electrical shock hazards. Are socket to outlet adapters Safe? As long as you don’t overload the … Continue reading →

Step Down the Voltage Install the smaller resistor first, stepping down your voltage from 12V to 11V. Once you’ve added the first resistor to your circuit, install the larger resistor to step the voltage down again. This resistor will take … Continue reading →

The series motor has poor speed regulation. When the load speed of the machine increases, the DC shunt motor keeps its constant speed from no load to full load. The dc series motor’s Torque drops sharply when the speed increases. … Continue reading →

There’s a reason class 0 devices are prohibited in a lot of countries. The advantage of not having a polarized plug is that a device can be plugged in each way which would be a pain for thinks like chargers … Continue reading →

Dust is the most common cause of laptop noises. Dust damages your system in various ways including obstructing your laptops fan, which causes it to make loud noises. Your laptop’s processor is essentially its brain; hence, we advise that you … Continue reading →

The Powerwall 2 actually comes in two different versions: an AC-coupled model that includes the inverter and a DC-coupled one that does not. Is the Powerwall DC-coupled? Tesla took the energy storage world by surprise with the release of the … Continue reading →

Battery start lawn mowers. Some new ceiling fans use BLDC motors. Fans found inside computers, induction cook tops etc also usually use DC motors. Battery powered power tools such as portable drills, cutting equipment and even some leaf blowers also … Continue reading →

Absolutely. Car fires can easily be started when a short circuit occurs in the 12volt DC system. If the current is sufficient to overheat the affected wires, these can ignite nearby flammable fluids, hoses, and other materials, starting a fire. … Continue reading →

Power inverter with DC plug. A direct current (DC) power socket is a power outlet that is found in automobiles and trucks. The socket is typically used for cigarette lighters, though most modern cars contain multiple outlets. What is a … Continue reading →
