ENGG1015 Tutorial

This document outlines critical components and safety measures for pre-project laboratory work in electrical engineering, specifically for building a Rube Goldberg machine. Key learning objectives include identifying appropriate components and understanding electrical safety, highlighting risks related to voltages as low as 50V. It discusses essential electrical units such as voltage, current, resistance, capacitance, and inductance, along with symbols used in circuit diagrams. Additional information on wiring color schemes and using a digital multimeter for troubleshooting is also provided.

Presentation Transcript

  1. 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

  2. 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

  3. 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

  4. Electrical Symbols

  5. Knowledge for the Pre-Project Lab • From circuit diagram to implementation

  6. Knowledge for the Pre-Project Lab • From circuit diagramto implementation

  7. Knowledge for the Pre-Project Lab Wire color scheme (red (DC), black (GND), yellow, blue, green) Wire to power supply Terminal Board Motor / Driver Sensor / Switch SS relay

  8. Digital Multi-meter (DMM) • Important debugging tool • Voltage DC: 2mv-1000v • Voltage AC: 2vac-750vac • Current: 2ua-10A • Resistance: 2-2m • BJT: beta test • Diode test
