Use a metal object or jumper cap to short-circuit the 2 Pin for about 5~10 seconds (at this time, that is, to clear the Real Time Clock (RTC) Random Access Memory). Plug in the power cord and turn on the PC. After the PC is turned on, there will be a prompt that the BIOS...
When you can't find plans, reading a circuit board is the only way to replicate or repair an old circuit. This can be a daunting and time-consuming task. Older circuit boards may contain unrecognizable parts that are no longer manufactured. Others may feature custom-integrated circuits that d...

how to find the input impedance of a circuit in ADS? is there a non polar capacitor in the library, i have only found capacitor with polarity. regards in s parameter simulation pallet there is a meas called Zin , u can use it to calculate the input impedance of the circuit u want ...
A flight controller, or “FC”, is the brain of an FPV drone. It’s a circuit board equipped with sensors that detect the drone’s movements and user commands. With this information, the FC adjusts the speed of the motors to move the drone in the desired direction. ...
Circuit breakers can malfunction, but it's rare. When a breaker won't reset, the problem is usually a bad connection or ground fault in the circuit. If you do isolate the problem to a bad breaker, you can't repair it. The only option is to remove the fau
When your lights go out, or appliances in the room suddenly stop working, it’s easy to panic or worry that you've lost power completely. Luckily, most often it’s just that a breaker has tripped, and it only takes a few steps to reset a circuit and restore power to your appliances...
In circuit diagrams, there are many electrical symbols that are used to represent different electrical components and devices. Here is an overview of the most used symbols in circuit diagrams. Resistor: A resistor is used to restrict the amount of current flow through a device. It is usually...
How to Find Cutoff Frequency There are many methods by which cutoff frequency can be calculated. Cutoff Frequency from Transfer Function The frequency response of a circuit, affected by varying sinusoidal source frequencies, is analyzed using a transfer function. This function is the ratio of the ...
To anyone who hasn't read this post it will look like some relay needed for operation of your circuit, especially if you mount a bogus reed-contact near the magnet (they might short your bogus reed, without avail). But when the lid moves off the box, the magnet moves...
