Questions[edit  edit source]
Ohm's Law[edit  edit source]
 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
Resistors[edit  edit source]
You have the following resistor color codes, what resistance do these correspond to?

 

 

 


Ports[edit  edit source]
 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?
