Part 1

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?

Part 2

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

brown	black	brown	gold

orange	orange	red	gold

brown	black	yellow	gold
