I was wanting to get some hands on experience with AC current circuits. I have been tinkering with DC circuits on a breadboard and was wondering what the best way to get AC on a breadboard would be. I can't really spend 200+ on a function generator. I might spend 30 or so on a kit function...

Homework Statement I built an amplifier in the breadboard so I want to test it out. I know there is a type of wire that one side can connect to the ipod and the other side separate into power (red in color) and ground ( black in wire) But I forgot the name of the wire, so I want to ask if...

This is only my second time using a breadboard, so bear with me. I have 4 resistors(black with silver stripe) and one small DC rotating motor. My goal is to get the DC motor to spin, yet I don't understand the diagram that I have including in the posting. Any advice would definitely be...

I have read that between breadboard nodes there can be as much as 25 pF of capacitance. I have a much better time understanding how parasitic induced voltages work, with respect to magnetic fields. I have a much harder time understanding how signals can become noisy due to parasitic...

I'm using a software to generatre sine waves for my op amp circuit. I know you have to use the headphone jack to output the signal, but I don't know how I would go about connecting my headphones to my circuit. The problem is I don't know how I have to cut my headphone wire for ground and etc...

I've got some D.C power supply connected to my breadboard, and there is definitely current going through it as I've put some resistors in series and parallel and checked the values on the multimeter vs my calculations and it seems to be alright. Now I put in a 5mm LED in series with a 100 ohm...

How do I model a breadboard in simulator. The capacitance, inductance. For example, if I place a DIP part on breadboard, how much capacitance should I add between the pins in the model? I think the typical capacitance is 2pf for adjacent pins. What about pins that are 3 pins apart?
