In my circuits/active devices course we had to make amplifier designs with various type of transistors (BJT, JFET, MOSFET). In each design the transistor beta parameter played an important role in deciding which resistors to use in the final amplifier circuit. This beta parameter changes widely...
Hello all, as the title states I'm trying to build an arduino powered chess board. The chess pieces will have magnets on the bottom and each square of the board will be equipped with a reed switch for detecting the presence of the magnetic field produced by the magnet. I recently tried this out...
Linking "Lower" Voltage and "Higher" Voltage systems?
I'm an undergraduate in EE (entering sophomore level) and I have been wondering about how a low voltage control system is connected to a relatively higher-in-voltage system. (An example would be how a thermostat turns off and on a heater or...
Right, what I meant is I would think current would flow more into whichever battery has the lower internal resistance. But it seems I don't have to take that into consideration at all...
Here is a recommended charger by the manufacturer. I see 600 mA is the output current. What should I notice...
Thanks, I've been coming to this forum for a while. Just haven't joined until today. Since that's the case, should I try and match the internal resistance of one battery to the other?
The way I'm thinking of it right now is if one of the battery's internal resistance is higher than the other's...
A friend of mine lost his battery charger for his airsoft gun and he naturally comes to me for electrical help. Problem is, I'm freshmen level right now. I looked up how to hack and build a basic battery charger, my question is do the internal resistance/impedance of the batteries matter when...
