Solid-state equipment usually uses polarized electrolytic capacitors to decouple DC, and that's bad. Not only are electrolytic capacitors far from optimum for coupling audio, they need a polarizing voltage which is usually absent in these designs. Most of these designs hope that no one notices, ...
Why are two-pronged plugs polarized so that they go into outlets only one way? Why electric current is a scalar quantity? Insulators also contain electrons, but they are not conductors, Why? Why k is infinity for conductors? Why do doors close so much faster and with so much les...
Why can't we use spherical conductors as capacitors? Why are some sunglasses polarized horizontally? Explain. Discuss the terminal speeds of big and small raindrops. What are the terminal speeds of raindrops have radii .002 m and .004 m? Why does the sky sometimes appear to be whitish? Wate...
Since they are non-polarized devices, they can be used in AC circuits. Most ceramic capacitors have a fairly high voltage rating. If the capacitor experiences a voltage between its terminals higher than its rated voltage, the dielectric may break down and electrons will flow between the thin ...
The Benefits of Extra Capacitors in FPV Drones The FET’s in our ESC are effectively switches. They turn on and off rapidly tens of thousands of times per second to drive the motors, which can generate a lot of electrical spikes and noise. As technology advances allowing for more powerfulmo...
Many have systems set this function to auto and forget that our computers are doing things in the background. Reply KRS March 6, 2013 at 7:34 am I’ve been told to shut down, disconnect the power cord and press the Start button, which discharges capacitors and flushes persistent ...
Differences Between Fuses and Circuit Breakers: Fuses and breakers are both electronic equipment designed to prevent fire and harm to human life due to power surges or cuts in cables. A fuse is a piece of metal that melts when overheated. This is the main problem with fuses...
Why can't we use spherical conductors as capacitors? Transformers are used to increase the voltage produced at power plants. Why is it desirable for the power to be transmitted at high voltage? (a) The transformer induction will be less resulting in le Why do you use a coil in a mag...
N-type and p-type semiconductor substances are used to make diodes. Some instances of semiconductor materials are silicon and germanium. A diode only permits a unidirectional current and has two terminals. A diode has absolute zero drops under the forward bias condition, it does not flow any ...
Why can't we use spherical conductors as capacitors? When connecting a simple AC circuit, why does not the polarity matter? What is the difference between the AC motor & DC motor? Why are the 3 Phase inverter circuits and position sensors needed in the brushless DC motors? Explain briefly....
