There are many more free electrons than holes, so the holes fill up very quickly. This creates depletion zones at the boundaries between n-type material and p-type material. In a depletion zone, the semiconductor material is returned to its original insulating state -- all the holes are ...
The following method assumes that you know how many amps you need for the gadget under power. If you know the watts go to Step A below. Step 1.Back of the envelope If the current drawn isxamps, the time isThours then the capacityCin amp-hours is ...
While a heat pump is far more energy-efficient than a traditional heating system (and many air conditioners, too), it’ll still be the most energy-hungry appliance in almost any home that uses one as the main HVAC system. The exact amount depends heavily on the following factors. Local ...
If the capacitor is bad, the motor won't have enough torque to turn over. Also check the governor to make sure it doesn’t stick open when the pump is off. Reply Snapperhead Posted: 8/19/2014 I have a 1.5 hp pump for an above ground pool. It doesn't start on it's own, ...
Q: How much does a car battery weigh? How many amp-hours does a car battery contain?A: The car battery's weight or mass depends on the size of the battery, but they are typically weighing between 30 and 50 lbs, with most approximately 41 lbs (14 kg to 22 kg). It isn't possible...
Soft soldering is a technique used to join wires, fix electronic components onto circuit boards and bond copper pipes together. This tutorial shows you how to solder step by step.
Second, the op-amps have the same part number. It’s true that this circuit uses two op-amps whereas the Howland pump uses only one, but the fact that both op-amps can be the same exact part is advantageous because you can use a dual-op-amp IC package and thereby minimize whatever ...
Measuring electricity is really easy—we're all familiar with electrical units like volts, amps, and watts (and most of us have seen moving-coil meters in one form or another). Measuring magnetism is a little bit harder. Ask most people how to measure the strength of a magnetic field (...

For many aspiring bloggers, niche selection is one of the most challenging dilemmas they face whenstarting a blog. They either have too many ideas, or — worse — they have no idea what kind of site they should build. It doesn’t help that there’s lots of contradictory advice out there...
