The good news is that you only need a voltage stabilizer for a LED TV if your home frequently experiences voltage fluctuations. A voltage fluctuation can decrease or increase the amount of voltage going into your devices; both are damaging … Continue reading →

If the 18v drill provides higher torque you should go for it. On the other hand if the 20v drill offers better torque you should favor it over its competition. The higher the torque of a drill the better results … Continue reading →

The terms AC and DC can describe signals as well. An AC signal is a current, voltage, or numerical sequence that consistently exhibits both positive and negative values, and a DC signal exhibits only positive values or only negative values. … Continue reading →

Temperature is probably the most common reason that smartphone batteries die unexpectedly. As mentioned, your battery is made possible by chemical reactions. If your phone becomes too cold, the reactions can slow down, causing your battery to shut off suddenly … Continue reading →

An electric motor, though, is as an alternating-current (AC) source. For the electric motor to provide DC energy, its output has to pass through an electronic circuit called a rectifier. An electric motor can be used in conjunction with a … Continue reading →

How can you tell which 12 volt wire is positive? If you see red and black wires in a pair the black is negative and the red is positive. Using a multimeter will tell you for sure. There is no … Continue reading →

Can you pat test phone chargers? PAT Testing a phone charger makes perfect sense as with any other portable electrical appliance, they can become damaged and faulty; which can result in damage, injury or worse!Providing the PAT Tester has passed … Continue reading →

Check the power outlet Make sure that you’ve connected your USB-C power adapter to a working power outlet. Unplug your USB-C power adapter from the power outlet, then plug in a known good device, such as a lamp or clock … Continue reading →

Nope DC (Direct current) doesn’t have any frequency or zero frequency. Only Alternative current (AC) will have frequency. D.C has zero frequency. From the graph of d.c, we know that, it is parallel to the time axis and never changes … Continue reading →

When an iPhone cable overheats, it does so inside of the cable, too far away from the iPhone to cause any real damage. The only exception, as we discussed, is when the lightning cable overheats inside your iPhone, in which … Continue reading →

The desktop computer power supply converts the alternating current (AC) from a wall socket of mains electricity to a low-voltage direct current (DC) to operate the motherboard, processor and peripheral devices. Why do computers run on DC? In ICs, Microprocessors … Continue reading →

DC(Direct Current) is not used over AC(Alternating Current) in transmission because DC goes heavy attenuation while transmission over long distance as we do not transform it from Low Voltage (at which it is being generated) to High voltage (for transmission … Continue reading →

Electrical connectors are classified into three types based on their termination ends: board-to-board connectors, cable/wire-to-cable/wire connectors, and cable/wire-to-board connectors. What are the 4 types of connectors? Connectors are used between two separate sentences. There are four types of conjunctions: coordinating, … Continue reading →

A cigarette lighter can only drain the battery when it is pressed in to heat up, it should spring back out once up to temperature and break the circuit. If you have a fault then it can drain the battery … Continue reading →

A Rectifier is a electrical device which converts alternating current (AC) To Directional current(DC) IN Computers. Who converts AC into DC? rectifierA rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), … Continue reading →
