Controlling impedance (resistance) is almost a given with today’s technology. One day, we are adding a wireless option to a common object and calling it the Internet of Things. The next day, we’re simply keeping up with the competition on processing the code. Days go by and the trend ...
can be reduced with alternate fuses, such as resettable fuses, which utilize a positive temperature coefficient to open the circuit when a larger than normal current passes through the device (the increased current level increases the temperature, resulting in a sharp increase in resistance). ...
For example, the physical resistance of the wires that connect circuit elements can cause significant changes in operating voltages and, thus, overall circuit performance. The variability of the manufacturing process can also create unexpected circuit behavior. To deal with these issues, late effects ...
by using partial circuit Ohm's law: R=U/I to measure the resistance value. Use the ammeter to measure the current through the unknown resistor at this voltage, and then calculate the resistance of the unknown resistor. Volt-ampereresistance measurementis...
The objective of a schematic is to make your circuitry easier to understand for you as a designer. Unnecessary net connections should be minimized. This is commonly observed when drawing the symbol of an integrated circuit (IC) on a schematic. ...
- load resistance, R=4.7ohm Since Vb = Va * [ R / (R+r) ], r = internal resistance Then, internal resistance of the battery can be determined to be around 240mOhm. Hence, my battery can theoretically discharge the current as high as 4.2V/0.24=17.5A (short circuit maximum current ...
Figure1: Low Pass Filter High Pass Filter A high-pass filter permits frequencies above a specified cut-off while suppressing those below the cut-off frequency before it passes on to the next circuit. Sometimes this filter is called a low-frequency attenuator. ...
Let’s take a minute to explain how they function. To quote Harvard Extension School’sofficial YouTube channel, the “difference in total charge inside and outside of the cell is called themembrane potential.” (The term “resting membrane potential” derives from this concept. Go figure.) ...

That buzzing noise can sound weird, especially when it’s louder with particular pieces of cookware for reasons that I have yet to figure out. On the other hand, I’ve decided that I like the beeps the touch controls make as I tap them; the experience feels a little like cooking on th...
