The original USB port can only charge a small single-cell Li-ion battery. Charging a 3.6V pack begins by applying a constant current to a voltage peak of 4.20V/cell, at which point the voltage peaks and the current begins to taper … Continue reading →

How do I charge my Panasonic video camera? Each Panasonic camera/camcorder is supplied with it’s own battery charger. Depending on the model the battery can be charged inside the camera/camcorder or outside using a special charger. We do not recommend … Continue reading →

The Shunt winding has a large number of turns so that it has appreciable inductance. When A.C is applied to a shunt motor, the large inductive reactance of shunt winding will reduce the field current too much. Consequently, Shunt motor … Continue reading →

Prone to underfitting Since linear regression assumes a linear relationship between the input and output varaibles, it fails to fit complex datasets properly. In most real life scenarios the relationship between the variables of the dataset isn’t linear and hence … Continue reading →

The Chevy Volt, Nissan Leaf and Tesla Roadster all use a super greenhouse gas known as HFC 134a as the refrigerant for their air conditioners. The liquid coolant is so potent that when it leaks into the atmosphere it traps … Continue reading →

It is called 240v because it is equivalent to 240v dc for heating and lighting. 240v is the ‘rms’ value. Rectified ac is often confused with dc, but is not the same thing. Some wallwarts produce rectified ac. Is 240V … Continue reading →

no. do not EVER do that. It will damage your router – they are designed to run at specific voltages, and devices such as routers don’t have the best voltage regulation circuitry. Can a power outage damage my router? The … Continue reading →

The short answer is that a good mid-range gaming laptop will last 3-4 years. For high-end models, it could serve you 4-6 years. In terms of its physical components, you can expect up to 10 years’ worth of service. Do … Continue reading →

The main factor that went into the choice of AC over DC was that AC is more efficient. Its ability to travel back and forth made gave it the ability to travel over longer distances. Thus making it able to … Continue reading →

Voltage regulation is the measure of how well a power transformer can maintain constant secondary voltage given a constant primary voltage and wide variance in load current. The lower the percentage (closer to zero), the more stable the secondary voltage … Continue reading →

5 Ways to Protect Your House and Appliances from a Power Surge Install a Whole-House Surge Protector. Have Added Protection for Specific Devices. Upgrade Your AC Unit. Unplug Devices During a Storm. Inspect Your Wiring. How do you protect appliances … Continue reading →

Polarized Receptacles The wider prong on the polarized plug will permit it to be plugged in only with the correct polarity. The narrower prong is the “hot” lead and the switch to the appliance is placed in that lead, gauranteeing … Continue reading →

Mobile charger contains a circuit called SMPS which converts 220v Ac to DC and then with a controller circuit it converts it to AC 5V at very high frequency in range of 30 to 40 kHz and then rectify it … Continue reading →

Most gas stations will have AA or AAA batteries, but they won’t be in anything more than a four-pack. If you’re looking for specialty batteries like 9volt, C, or D cell batteries, then you’ll need to visit the auto part … Continue reading →
