Why is a microcontroller pin connected to ground via capacitors ...
Here Vref of the MCU is connected to ground via two parallel capacitors. This microcontroller is chinese-made so its datasheet is available, but not very detailed. The datasheet shows that Vref is internally connected to VDD/VCC which is 3.3 V, though I am not sure, because I think it should be zero, because it compares an input analog signal to detect its +ve …
Star and Delta Connection of Capacitors

Why does the distance between the plates of a capacitor affect its ...
Remember, that for any parallel plate capacitor V is not affected by distance, because: V = W/q (work done per unit charge in bringing it from on plate to the other) and W = F x d. and F = q x E. so, V = F x d /q = q x E x d/q. V = E x d So, if d (distance) bet plates increases, E (electric field strength) would drecrese and V would remain the same. Share. Cite. Follow …
Why does a floating capacitor act differently than a grounded capacitor?
I''m having difficulty understanding why a floating capacitor will store less charge than a grounded capacitor. Imagine you have two parallel plates and a low DC voltage source like 5V, with the negative side connected to neutral ground, and that you have two different ways of wiring it:
electric circuits
As the capacitor gets larger, the amount of voltage droop will be smaller (the slope of the green curve will be less if the capacitance is greater as the capacitor can provide more charge / current without the voltage decreasing). Incidentally, sometimes people will put capacitors of different types in parallel. For example, a large ...
What are Capacitors in Series and Parallel?
Introduction. Capacitors are components that store electricity and electrical energy (potential energy), and play an important role in circuits such as tuning, bypassing, coupling, and filtering.Capacitors are connected in parallel to increase capacity, and capacitors are connected in series to decrease capacity. When the capacitor is connected in series in the …

Fundamentally knowing when to use capacitors / inductors
So, if you have an AC signal, you can put a series capacitor to make sure no DC goes through and hurts the rest of your circuit. Inductor: If you have unwanted noise, you can use an inductor in series in a similar way to a capacitor in parallel (shunt). So, your 5V line is going through a long cable and may have picked up some noise along the ...

Charge Distribution on a Parallel Plate Capacitor
Ignore inner and outer surfaces. There is just one surface. Imagine a single, infinite plane with some positive charge density. You can easily show there would be an electric field of constant strength*, perpendicularly out of the plane all the way to infinity on both directions.. Now imagine a single, infinite plate with the same negative charge density.

why do we connect capacitors to the crystal in the microcontroller ...
The capacitors are there to resonate with the crystal inductance and cause the crystal to oscillate on its fundamental parallel-resonant mode. The reason that there are two capacitors in series is to create a network that creates a 180 degree phase inversion at resonance, because the amplifier (inverter) has a 180 degree phase inversion between its input …
