Questions
Ohm's Law
- A computer serial port cable has a few requirements: the signal is 5 volts, and the total current flowing into the port can be up to 2 milliamps. If the current is too high, the circuit will be ruined. How much resistance must a serial cable have at 5 volts to keep the current below 2 milliamps?
- If we have a circuit with a set resistance R, we want to change the voltage and measure the current. Which of the following shapes is our graph likely to have:
- Parabola
- Hyperbola
- Line
- Sine Wave

Ports
- We have a sensor that outputs values between 0 and 116. How many parallel input ports do we need?
- If we have the statement "DIRS = %1100110101001110", what ports are inputs, and what ports are outputs?
