WebA.3 What is the max V? A.4 What is the operating/typical VF? A.5 Calculate R for Vs = 5 V using the operating IF and operating Vp A.6 Calculate PD (power dissipation) for the … WebI would say that depends heavily on what you need it for. Often the expensive spices are part of some e.g PCB design tool. I'm just trying out MultiSIm from NI (expensive orcad type tool), and it has lots of pretty virtual instruments (e.g scope, distortion analyser, etc) and monte carlo analysis (which LTspice does not have a "convenient" version of - it does …
What should my resistor wattage be to run a LED on 240VAC?
Web7 apr. 2024 · LTspice® is a powerful, fast, and free SPICE simulator software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits. Its graphical schematic capture interface allows you to probe schematics and produce simulation results, which can be explored further through the built-in … Web21 jul. 2016 · Slight correction: 240VAC is RMS voltage, and has a peak voltage of 240 * sqrt (2) = 340Vpk. Your resistor needs to be 18.8k to limit current to 18 mA, and will dissipate ~6.1W peak or 4.3Wrms. You still need (at least) a 5W resistor, however. Jul 20, 2016 at 0:13.
