Introduction to Robotics Electrical Components: Lecture (For Students) (For Teachers) —

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:
1. Parabola
2. Hyperbola
3. Line
4. Sine Wave

You have the following resistor color codes, what resistance do these correspond to?

1.


brown	black	brown	gold

2.


orange	orange	red	gold

3.


brown	black	yellow	gold

4.


green	green	blue	gold

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