Hi everyone,

I am new to the forum and i am looking at a software that will help me simulate circuits. i have been using Pspice but I am not really happy with all its features. can someone please suggest something better for me?
Eagerly awaiting a reply.

thanks

Go to the Linear website (www.linear.com) and download LTSpice. It is really good and completely free.
 
Hey thank u. I appreciate that. I will give it a try and write back again.
 
Thank You! You just made my day.
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Two capacitors, etc.'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
