7. OHM’S LAW READING Ohm’s Law states that the current in a circuit is directly proportional to the voltage impressed across the circuit, and is inversely proportional to the resistance of the circuit. The relationship among voltage, current, and resistance is called Ohm’s Law. Ohm’s Law in short, current=voltage/resistance. The relationship among the units of measurement for current, voltage and resistance is: 1 ampere=1 volt/ohm OHM’S LAW QUESTIONS DIRECTIONS: Fill in the blank from the reading 1.The relationship among current, voltage, and _________________ is called Ohm’s Law. 2.State Ohm’s Law _______________________________________________ 3. How can you express Ohm’s Law mathematically: 4.

8. OHM’S LAW AND ELECTRICAL SHOCK READING The damaging effects of electric shock are the result of current passing through the body. From ohm’s law, we can see that a damaging electric current depends on the voltage applied, and also on the electrical resistance of the human body. The resistance of the human body depends on its condition and ranges from about 100 ohms if it’s soaked with salt water to about 500,000 ohms if the skin is very dry Drops of water that collect around on/off switches of devices such as a hair dryer can conduct current to the user. Handling electric devices while taking a bath is extremely dangerous. OHM’S LAW QUESTIONS DIRECTIONS: Fill in the blank from the reading 1. The damaging effects of electric shock are the result of _________________ passing through the body. 2.Is the following sentence true or false? The resistance of your body is much greater when your soaked with water than when your skin is dry. _________________ 3.Explain why it is dangerous to handle electric devices while taking a bath. _____________________________ _ ___________________________ _ At the end of the lesson I should be able to: understand Ohm’s Law and the variables associated with it.

9. OHM’S LAW AND ELECTRICAL SHOCK READING If a bird is perched on a high line wire, the bird will not receive a shock unless there is a difference in potential between one part of its body and another part. Mild shocks occur when the surfaces if appliances are at an electrical potential different form that of the surfaces of another nearby. OHM’S LAW QUESTIONS DIRECTIONS: Fill in the blank from the reading 4. Is the following sentence true or false? A bird perched on a high-voltage wire is not shocked because there is not a potential difference between one part of the body and the other part. TRUE FALSE 5. What is the purpose of third prong on a three-prong electric plug? A: To use as a grounding wire so that shocks or electrical fires do not occur.
