1 STARTER What is the formula for Ohm’s Law? What is the formula for Ohm’s Law? What is the formula for Electrical Power? What is the formula for Electrical Power?

2 OHM’S LAW & ELECTRIC POWER DAY 42

3 PARALLEL VS SERIES What is the difference between a series and parallel circuit? What is the difference between a series and parallel circuit?

4 PROBLEM SOLVING Two bulbs connected in a parallel shine more brightly than when they are connected to the same voltage source on series. Explain why this doesn’t violate the law of conservation of energy. Two bulbs connected in a parallel shine more brightly than when they are connected to the same voltage source on series. Explain why this doesn’t violate the law of conservation of energy. You plug in a string of Christmas lights and notice that the entire string turns off when you remove one bulb. Explain why this happens. You plug in a string of Christmas lights and notice that the entire string turns off when you remove one bulb. Explain why this happens.

5 REVIEW Directions: Copy and Answer the following statements using the terms Series or Parallel Circuits. 1. Only one path for the electricity. 2. Dependent paths. 3. How your house is wired. 4. Independent current paths. 5. Can turn off one light without others turning off. 6. If you turn off one light, all the lights turn off. 7. More than one path for the electricity to flow.

6 PRACTICE!!! A stereo receiver uses a current of 2.2 amps from a 120-volt line. What is its power? A stereo receiver uses a current of 2.2 amps from a 120-volt line. What is its power? A television connected to a 120-volt line uses 102 watts of power. How much current flows through it? A television connected to a 120-volt line uses 102 watts of power. How much current flows through it?
