ENGG1015 Tutorial
Pro-Project Laboratory and Project 15 Oct (Supplementary notes, may be obsolete,
NOT for examination) Learning Objectives
Identify components that can be used in the pre-project labs and project (i.e. Build a Rube Goldberg Machine)
Identify electrical safety rules, electrical units, electrical symbols rules
Electrical Safety
5-10 ma can cause death Skin resistance can range from 1kΩ for wet
skin to 500kΩ for dry skin. Death can result from as low as 50 volts Body can sense 9 volts under the right
conditions
Report TA or technician for any emergency case
Electrical Units
Voltage (V): volts (μv → kv) Current (I): amperes (amps), milliampere (ma
10-3) Resistance (R): ohms Ω, k-ohms (k 103), meg
ohms (m 106) Capacitance (C): farad, microfarad (µf 10-6),
nanofarad (nf 10-9), picofarad (pf 10-12) Inductance (H): henry, millihenry, microhenry Frequency (freq.): mhz, ghz 109
Knowledge for the Pre-Project Lab
Terminal Board
Sensor / Switch
Motor / Driver
Wire to power supply
Wire color scheme (red (DC), black (GND), yellow, blue, green)
SS relay
