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 →

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 →

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 →

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 →

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 →

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 →

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 →

The only way to step down voltage without a transformer, is to add resistance to the circuit, whether that is by adding more length to the feeder, which would increase voltage dropvoltage dropVoltage drop is the decrease of electrical potential … Continue reading →

Electrical Energy in Circuits In other words, Energy = power x time and Power = voltage x current. Therefore electrical power is related to energy and the unit given for electrical energy is the watt-seconds or joules. Electrical power can … Continue reading →

A regulated power supply converts unregulated AC (Alternating CurrentAlternating CurrentAlternating current can be measured by using moving iron type ammeter. Although pmmc instrument can be used to measure alternating current but in this case the alternating current first been rectified … Continue reading →

The disadvantage of this is that it can be difficult to smooth out this large ripple frequency in much the same way as for a half wave rectifier circuit. Also, capacitor C2 must have a DC voltage rating at least … Continue reading →

A 6-volt positive ground system runs the positive side of the battery to the frame of the car, causing the frame and chassis to carry the current (this was thought to reduce corrosion). When an accessory is wired back to … Continue reading →

What are the front panel connectors that we need to connect to the motherboard? The Front Panel Connectors, also known as the Front Panel Header or FPanel, is a block of connectors on a motherboard that control the power on, … Continue reading →

The trick is to jump from the positive terminal of the 12-volt battery to the positive terminal on the 6-volt. The negative jumper is connected to the negative terminal on the 12-volt battery. Can I use a 12 volt jump … Continue reading →
