  1. Electrical Circuits Utah Underwater Robotics Instruction Slides

  2. Basics • What is electricity? • Flow of electrons from one place to another. • Electrons must be able to move. • Voltage (V), Current (I), Resistance (R) • Fluid pump analogy.

  3. Analogy • Pressure – Voltage • Water Flow – Current • Hose Size – Resistance

  4. Basics • Units (V, A, W) • Ohm’s law Voltage = Current * Resistance V=IR

  5. Components DPDT (Double Pole Double Throw) Switch Resistor LED (Light Emitting Diode) Fuse

  6. Schematics 9V Battery 30 mA LED R = V/I 9V/0.03A = 180W

  7. Soldering • Tools • Procedure • Safety
