So I'm using an arduino, but I want to drive more current through the motors, so that they can go faster. Imagine that bipolar source to be the arduino.
So, imagining I have 4.7uA (Ib) at the output of arduino Ic would be 100*Ib (470uA), right? Another disclaimer is, ignore the phase, I know it would be off by 180 degrees, so I would need another transistor. So, if it was low, I would get 10V, if it was high, I would get 1k*100*Ib? If I wanted that to be zero, I would calculate the value of R1 by doing this operation 10/(100*Ib). Multisim doesn't seem to be giving me clear answers, and I've search for answers online and I couldn't get if I'm right or not. Also, if the resistor was low, I wouldn't get 0V, would it be possible to get 5V ( just an example) ?
Thanks in advance.
