Choose the motor controller voltage range to match your motor’s nominal voltage . Find out how much current per coilyour motor requires, and find out how much current (per coil) the stepper motor controller can provide. If you cannot find … Continue reading →

Yes the speed of the DC motor is increased by increasing the armature voltage. Therefore, the speed of the motor is proportional to the applied DC voltage if the field flux is constant. The torque of the motor is proportional … Continue reading →

Can you convert a 12V ride-on to 24V? It is possible to hook up two 12V batteries to create a 24V ride-on toy vehicle. The trick is to pack the two batteries close together and hook them up in an … Continue reading →

As there will be a bridge rectifier in the device that you are powering, if you used a 24V DC, instead of 24V AC supply, the voltage inside the unit will be down by 29% than normal, this is because … Continue reading →

You would install the Buck Converter between the solar panel (the input line to the converter) and the battery (the output line from the converter.) As solar energy flows down the circuit, it would enter the converter, which would limit … Continue reading →

If it reads “Plugged in, Charging” then your battery is working, even if the charge capacity has greatly decreased since you bought the laptop. If the status message reads “0% Available (Plugged in, Not Charging),” then power is not getting … Continue reading →

Yes, but the drill will have greatly diminished power. Ensure that the charging of the battery is independent of the drill. A 24 V charging circuit will overcharge a 18V battery and likely cause a fire. Can I run a … Continue reading →

You can use as many branches of 3 leds as the power supply can power. How many LEDs can you power with 12V? Since the LEDs are in series, they all have the same current through them, and will therefore … Continue reading →

Band Gap and Photon Wavelength Relation LED color Wavelength Range (nm) Semiconductors Used Red 625-760 AlGaAs Orange 600-625 GaAsP Yellow 577-600 AlGaInP Green 492-577 GaN Which LED has the highest energy gap? between energy and color of light. 9. In … Continue reading →

A 24V Power supply can change AC to DC. In addition to converting the AC power to DC power, the voltage level can be adjusted at the same time. Some devices need DC but only have access to the AC … Continue reading →

We often get asked “How do you reduce 24Vdc to 12Vdc” and the answer is pretty easy – you use a DC to DC converter which has a 24Vdc (nominal) input with a regulated 12Vdc output. If you have a … Continue reading →

Can you fix a laptop charger port? To fix a laptop charger port, you need to first identify the source of the problem. If the power jack is connected to the motherboard, you can easily remove and replace it. On … Continue reading →

Xiaomi confirms 120W fast charging is safe and won’t harm batteries. Can you charge phone with 120W? iQOO 9 – 120W fast charging The company claims the 120W fast charger can charge the iQOO 9 from 0-100 in 19 mins. … Continue reading →

If the headphone jack on your laptop stops functioning, your best option is getting a USB to headphone jack dongle or some bluetooth headphones (if your laptop has bluetooth.) The jack port is soldered to the motherboard in most cases … Continue reading →
