  1. POWER

  2. POWER THE RATE OF DOING WORK OR CONVERTING ENERGY. Power = Work / Time Power = Energy / Time UNIT- WATT = JOULE PER SECOND

  3. POWER Watt Demonstration: Lift a 1-N mass a distance of 1 meter, and you have done 1 Joule of Work. Do this once each second, and your power output is 1 Watt.

  4. POWER Light bulbs are rated by the power used.

  5. POWER Power = Current × Voltage What are the units for Current, Voltage, and Power? Ampere = coulomb / second Volt = joule / coulomb

  6. POWER What is a Volt X Ampere ? Volt X Ampere = joule/coulomb X coulomb/second Volt X Ampere = joule/second = watt

  7. POWER A PAIR OF LEMON BATTERIES GENERATED ABOUT 0.5 MILLIWATTS AN XMAS BULB REQUIRES ABOUT 0.5 TO 1 WATT

  8. POWER ACTIVITY HAND HELD GENERATOR
