Light-dependent resistors, also known as LDRs or photoresistors, are electrical components that detect light and modulate the function of a circuit based on the levels of light. What Does LDR Mean Light-dependent resistors are frequently employed in electronic circuit designs to sense the presence or amount of light. The light-dependent resistor, LDR, … [Read more...] about What Does LDR Mean

PNP is the acronym for Positive, Negative, Positive. Also referred to as sourcing. When undriven, a PNP input on an IO Module is dragged up to a high state, such as +5V. Digital signals are typically NPN or PNP. Sensors are a sample of NPN or PNP devices. What Does PNP Stand For in Electronics In a PNP transistor, the current passes from the collector to the … [Read more...] about What Does PNP Stand For in Electronics

You can use an ohmmeter or multimeter to check a transformer. Simply connect directly the red and black pins of your ohmmeter to the different ends of the transformer's wiring to test it. To check the transformer with a digital multimeter, you have to follow some simple steps.  How to Test a Transformer Transformers are electrical devices that allow electrical … [Read more...] about How to Test a Transformer

MMF stands for magnetomotive force is a component of the equation of magnetic flux regarding magnetic circuits. It is analogous to electromotive force and it drives the magnetic flux through a magnetic circuit. What Does MMF Mean MMF or magnetomotive force talks about the magnetic flux in a magnetic circuit. It is a component of magnetic circuit analysis and can be used … [Read more...] about What Does MMF Mean

An inductor can be used to charge a capacitor instead of a resistor. You can charge the capacitor to a higher voltage than the source by connecting a diode in series with the inductor. The diode disengages the capacitor from the source precisely as the inductor current drops to zero and the capacitor is fully charged, forming a series resonant circuit. How to Charge … [Read more...] about How to Charge Capacitor Without Resistor
