The remote variable resistor functions as a voltage-controlled resistor whose resistance changes based on an applied voltage.

Here’s a clever hack. Simple, elegant, and eminently cost-effective: using an SMD capacitor to hold your flash media in place ...

Extending Woodward's original "Flip ON Flop OFF" for AC voltages, switching power ON and OFF using a pushbutton or a ...

Figure 2 TBH principle sums two 8-bit PWM signals in one 16-bit DAC = Vref (MSBY+LSBY/256)/256. The asterisked resistors are ...

Find out how you can change a circuit by adding items like switches with this Bitesiz KS2 science animation and a fun activity.

A very simple circuit loss model and an efficiency formula are given for regulated pulsewidth modulated (PWM) dc-to-dc converters which can be used by manufacturers of off-the-shelf converters to ...

In this brief, we designed, constructed, and analyzed a frequency-tunable metamaterial resonator. The proposed design consists of an S-shaped resonator, a ground frame, and a feeding transmission line ...

Researchers at the University of Alabama have developed a low-cost triboelectric nanogenerator (TENG) using store-bought ...
