• How do Watts Law and Ohms Law relate to the
  project?
• Why is this information essential in designing a
  solar LED lighting system?

I V R
W I E
Watts Law W represents Watts I represents
Current, measured in Amperes (Amps) E
represents Volts, The difference in energy
between 2 points.
Ohms Law I represents Current, measured in
Amperes (Amps) V represents Volts, The
difference in energy between 2 points. R
represents Impedance, measured in Ohms O

• What is a cell what is a battery, and what is
  the difference between the two? A cell is a
  device that chemically stores and produces
  voltage with an electrode and electrolyte. A
  battery is a bank of 2 or more cells that work
  in unison to generate a greater voltage or
  amperage depending on the arrangement of the
  battery
• What are the symbols for both a cell and a
  battery in an circuit?
• What is a resistor?
• What is the symbol for a resistor in a circuit?
• What is the definition of a diode?
• What is the symbol for a diode in a circuit?
• What does the Term LED stand For? Light
