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 →

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 →

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 →

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 →

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 →

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 →

Highest-revving car engines ever made Lamborghini Huracan STO – 8,500rpm. McLaren 570S – 8,500rpm. Audi R8 V10 – 8,700rpm. Ferrari F12tdf – 8,900rpm. Ferrari 458 – 9,000rpm. Lexus LFA – 9,000rpm. Porsche 911 (991) GT3 – 9,000rpm. Porsche 918 Spyder … 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 →

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 →

Larger units in the 24 volt charger models are about 25 to 40 amps output (except commercial, 220 VAC input types, or 3 phase). These are used in large amp hour battery banks, or applications desiring faster recharge times (possibly … Continue reading →

The size of the charger always matches the size of the battery so since a MacBook battery is many times bigger than an iPhone battery, the MAcBook charger has store be many times bigger so that it supplies the greater … Continue reading →

A laptop typically uses about 50 watts of electricity, the equivalent of 0.05 kWh. How many watts does a laptop use per hour? As we already know that a laptop only consumes for up to 60 watts per hour, a … Continue reading →

The main difference between a MagSafe case and a non-MagSafe case is the ring of magnets that assist in the attachment of other accessories. However, it’s not as simple as attaching magnets to the case. There are specific thicknesses and … Continue reading →

Why does my Mac get so hot? Software and hardware issues alike can cause MacBooks to overheat. Although older machines tend to run hot more often, even the latest MacBook models will heat up when memory-intensive tasks overburden the processor, … Continue reading →

To see your charging status in Today View or on the Home Screen, add the Batteries widget: Go to Today View or the Home Screen page where you want to add the widget, then touch and hold the background until … Continue reading →
