While reading specs of a new ASUS Wi-Fi router – it said to have 2 GBPS throughput. How could it reach such throughput if all the WIFI bandwidth should be small and close to 2.4 GHz and 5 GHz?

I have two lead-acid batteries of the plate type, 12 V/100 Ah each, used for an inverter. I want to store these batteries for a year or two in a disconnected state. A friend of mine told me it’s …

I am aware of the dependence of some ceramic capacitors (e.g. X7R) capacitance on DC voltage. I assumed that if a high enough AC voltage is applied, capacitance changes in its rhythm causing …

I have a question about routing style of pads with the same functionality belonging to one chip. I draw a picture in Paint (fictional IC; let it be the SOIC8 footprint). GND is only as example (it can …

When simulating the 2N7000 in CircuitLab, I was surprised to see that the current was lower than expected for my circuit (90mA at the drain) when the gate is at 3.3 V. So, I built a quick breadboard …

I have seen much info explaining that the inputs of unused gates in a multi-gate IC (say, 74LS00, which is a quad-gate, where only 3 gates are used) should not be left floating, but I cannot find any …

I have been trying this exercise for a while and I can’t solve it. What they ask me to find is $$\frac{V_2\left(s\right)}{V_s\left(s\right)}=?$$ My best attempt has been the following \begin{array}{…

The official page of Wikipedia mentions that reverse saturation current is a part of minority current caused by the drift of charges. I am really confused about this. In class, we have been taught the …

I know the reasons for using terminating resistors on a CAN bus and how important it is. But why 120 ohm? How did this value come up? Is there any specific reason to use 120 ohm?

I would like to know how the mechanical rotor frequency [Hz] can be obtained from the electrical stator frequency [Hz]? This is no homework! I have consulted several books as well as the web but could …

I know mAh tells how much milliamperes a battery can deliver in an hour. But does that also tell how many hours the battery would last? Sorry but I don’t really get it. If we’re talking about a water …

So this seem like a simple question, but I’m trying to flip components in the schematic editor. If I select a component then use the keyboard shortcut X or Y, it brings up a menu and does not slip the …

Based in one of the answers given to me I made the input signal be a sine with a 1V offset and 1 V amplitude. If I were to apply the equation given from the user that answered what would the interval …
