The alkaline variant of the 9V battery is also referred to as 6LR61 and 006P. Other industry names for the 9V battery can be Duracell MN1604, Rayovac A1604, Energizer 522, Varta 4922, MX2400, 1604A, Radio Battery, Smoke Alarm Battery, 9V … Continue reading →

The only way to change to a cheaper electricity tariff is to switch – either by switching your electricity tariff or by changing electricity supplier entirely. While the main reason most people switch is to get cheaper electricity, there are … Continue reading →

If a high voltage needs to be generated from a low voltage, a boost converter can be used. This represents one of the three elementary switching regulator topologies and requires only two switches, an inductor, and input and output capacitors. … Continue reading →

How do I adjust the voltage on my power supply? Although there are +/- output models that cannot be adjusted, the output from most Power Supplies can be adjusted by turning the voltage output adjuster (V. ADJ). The voltage will … Continue reading →

Most Arduino boards have an external voltage input, and a range of 7-12V is recommended. So 9V seems perfect. The problem is that most Arduino boards use a linear regulator to drop that 9V to 5V. If you are drawing … Continue reading →

A computer’s CPU is one of its most reliable parts. The CPU will hardly fail unless its major components, including the CPU fan, power supply for the system, and the hard drive, fail. The lifespan of a CPU is affected … Continue reading →

Ohm’s Law dictates that for an equal amount of power in a circuit, a doubling of the voltage halves the amount of current required. Simply put, higher current requires larger wires. Thus, the change to 12 volts meant less copper … Continue reading →

What do I plug into ATX 12V? You’re currently looking at the “PCI-Express 8-pin & 6-pin compatible.” This plugs in to video cards. You want the “EPS/ATX12V 8-pin & 4-pin compatible.” This is what you’re going to plug into your … Continue reading →

Can a transformer be used with AC and DC? A transformer is a device which step-up or step-down the level of AC current or voltage without changing the primary (i.e. input source) frequency. Transformer only works on AC and can’t … Continue reading →

Along the edge of the ENERGIZER 9 volt battery is a crease where the case is joined together. It is basically just crimped together to form a seal. Using the needle nose pliers and if needed, a small screwdriver, carefully … Continue reading →

Mobile phones chargers these days work on SMPS. In these devices the ac is rectified and filtered to give high voltage dc. This high voltage dc is fed to a HF oscillator. The output of the HF oscillator is stepped … Continue reading →

Virtually all boats under 40 feet or so that have an electrical system operate at a nominal voltage of 12 volts. That is, they use a battery that has a fully-charged potential of 12.6 volts, and the loads and charge … Continue reading →

Solenoids are electromechanical devices that convert AC or DC electrical energy into linear motion. They usually consist of a helical coil wound concentrically around a movable cylinder, called the armature, made from a ferromagnetic material such as iron or steel. … Continue reading →
